∠x and ∠y are complementary.

∠x = (2w + 8)˚ and ∠y = 14 ˚ What is the measure of ∠x?

Angle Relationships $100

next

∠x and ∠y are complementary.

∠x = (2w + 8)˚ and ∠y = 14 ˚ What is the measure of ∠x?

Angle Relationships $100

(2w + 8) + 14 = 90

2w + 22 = 90

-22 -22

2w = 68

w = 34

∠x = (2w + 8)˚

∠x = 2(34) + 8

∠x = 68+ 8

∠x = 76˚

∠h and ∠j are supplementary.

∠h = 123˚ and ∠j = (12+3x)˚ What is the measure of ∠j?

Angle Relationships $200

next

∠h and ∠j are supplementary.

∠h = 123˚ and ∠j = (12+3x)˚ What is the measure of ∠j?

Angle Relationships $200

(12 + 3x) + 123 = 180

3x + 135 = 180

-135 -135

3x = 45

x = 15

∠j = (12 + 3x)˚

∠j = 12+ 3(15)

∠j = 12+ 45

∠j = 57˚

Lines l and m are parallel. Angle 6 is supplementary to which angles?

∠ 2

∠ 5

∠ 1

∠ 8

Angle Relationships $300

$300

Which angles are adjacent?

a) ∠ HIK and ∠JIF

b) ∠ HIK and ∠KIJ

c) ∠ HIK and ∠EFI

d) ∠ HIK and ∠DFG

$400

x+5 + 2x-2 + 90 = 180

3x + 93 = 180

3x = 87

x = 29

So Angle M is 2(29) – 2 or 56 degrees

A cone has a height of 3.2 inches and a volume of 53.59 cubic inches.

Find the radius.

Volume $500

next

Cone:

V = (1/3) x 3.14 x r2 x h

53.59 = (1/3) x 3.14 x r2 x 3.2

53.59 = 3.35 x r2

16 = r2 …so r = 4 inches
