.Answer:

A)

y = 60°

B)

x = 11

∡YXW = 82°

∡WXZ = 8°

Explanation:

A)

y, x are complementory angles

then:

x + y = 90

.y = 2x

then:

x + 2x= 90°

3x = 90°

x = 90/3

x = 30

y = 2x

y = 2*30

y = 60°

B)

Angle YXW an angle WXZ are complementory angles:

then:

(7x+5) + (3x-25) = 90°

7x + 3x + 5 - 25 = 90

10x -20 = 90

10x = 90 + 20

10x = 110

x = 110/10

x = 11

then:

  • angle YXW:

7x+5 = 7*11 + 5 = 77 + 5 = 82°

  • angle WXZ:

3x - 25 = 3*11 - 25 = 33 - 25 =
