  2. Name: ___________________________ Warm-Up 2. If you place a 39-foot ladder against the top of a 34-foot building, how many feet will the bottom of the ladder be from the bottom of the building? Round to the nearest tenth of a foot. You can draw a picture to help. 3. You start driving west for 8 miles, turn left, and drive south for another 11 miles. At the end of driving, what is your straight line distance from your starting point? Round to the nearest tenth of a mile. You can draw a picture to help. • Which of the following sets of numbers could represent the 3 sides of a right triangle?

  3. Answer Key

  4. Answer Key The bottom of the ladder will be 19.1 ft from the bottom of the building.

  5. Answer Key At the end of driving, you are 13.6 mi from your starting point.

  6. Steps to follow with word problems: Step 1: Draw a picture. Step 2: Fill in the given information on the picture. Step 3: Identify the Legs and Hypotenuse. Step 4: Substitute the legs and Hypotenuse in to the formula. Step 5: Solve

  7. Let’s try one together. A baseball diamond is a square that is 90 ft on each side. What is the distance a catcher has to throw the ball from home to second base?

  8. Let’s try one together. A baseball diamond is a square that is 90 ft on each side. What is the distance a catcher has to throw the ball from home to second base? Step 1: Draw a picture. 2nd X base Home X plate

  9. Let’s try one together. A baseball diamond is a square that is 90 ft on each side. What is the distance a catcher has to throw the ball from home to second base? Step 1: Draw a picture. 2nd X base 90 ft. Step 2: Fill in the given informtion on the picture. 90 ft. Home X plate

  10. Let’s try one together. A baseball diamond is a square that is 90 ft on each side. What is the distance a catcher has to throw the ball from home to second base? Step 1: Draw a picture. LEGS 2nd X base 90 ft. Step 2: Fill in the given informtion on the picture. Hypotenuse 90 ft. LEGS Home X plate

  11. Let’s try one together. A baseball diamond is a square that is 90 ft on each side. What is the distance a catcher has to throw the ball from home to second base? Step 1: Draw a picture. LEGS 2nd X base 90 ft. Step 2: Fill in the given information on the picture. Hypotenuse 90 ft. Step 3: Identify the Legs and Hypotenuse. LEGS Home X plate

  12. Let’s try one together. A baseball diamond is a square that is 90 ft on each side. What is the distance a catcher has to throw the ball from home to second base? Formula: a2 + b2 = c2 902 + 902 = c2 Step 4: Substitute the legs and Hypotenuse in to the formula.

  13. Let’s try one together. A baseball diamond is a square that is 90 ft on each side. What is the distance a catcher has to throw the ball from home to second base? Formula: a2 + b2 = c2 902 + 902 = c2 8100 + 8100= c2 16200 = c2 16200 = c2 127.3 ft (rounded to nearest tenth) Step 4: Substitute the legs and Hypotenuse in to the formula. Step 5: Solve

  14. Let’s try another one. A 35-foot ladder is leaning against the side of a building and is positioned such that the base of the ladder is 21 feet from the base of the building. How far above the ground is the point where the ladder touches the building?

  15. Let’s try another one. A 35-foot ladder is leaning against the side of a building and is positioned such that the base of the ladder is 21 feet from the base of the building. How far above the ground is the point where the ladder touches the building?

  16. Let’s try another one. A 35-foot ladder is leaning against the side of a building and is positioned such that the base of the ladder is 21 feet from the base of the building. How far above the ground is the point where the ladder touches the building?

  17. Let’s try another one. A 35-foot ladder is leaning against the side of a building and is positioned such that the base of the ladder is 21 feet from the base of the building. How far above the ground is the point where the ladder touches the building? Formula: a2 + b2 = c2 212 + b2=352 441 + b2 = 1225 -441 = -441 28 feet above the ground. b2 = 784 b = 784 b = 28 ft

  18. Here is a tricky one for you. Two friends start from the same spot with one walking south and the other one walks east. After twenty minutes they are 1.3 miles apart. If the first friend only traveled 0.5 miles, how far did the second friend go?

  19. Here is a tricky one for you. Two friends start from the same spot with one walking south and the other one walks east. After twenty minutes they are 1.3 miles apart. If the first friend only traveled 0.5 miles, how far did the second friend go?

  20. Here is a tricky one for you. Two friends start from the same spot with one walking south and the other one walks east. After twenty minutes they are 1.3 miles apart. If the first friend only traveled 0.5 miles, how far did the second friend go? 1.3 0.5

  21. Here is a tricky one for you. Two friends start from the same spot with one walking south and the other one walks east. After twenty minutes they are 1.3 miles apart. If the first friend only traveled 0.5 miles, how far did the second friend go? Formula: a2 + b2 = c2 0.52 + b2= 1.32 0.25+ b2 = 1.69 -0.25 = -0.25 b2 = 1.44 b = 144 b = 1.2 miles The second friend walked 1.2 miles 1.3 0.5
