Find the missing values in the following figures​
jekas [21]

Answer:

15.

  x = 40/9 = 4 4/9

  z = 24/5 = 4 4/5

17.

  x = 50

  y ≈ 11.5

Step-by-step explanation:

15. Corresponding segments are proportional:

  top right side / whole right side = x / 8

  5/(5+4) = x/8

  x = 8(5/9) = 40/9

  x = 4 4/9

__

  right side bottom / right side top = z / 6

  z = 6(4/5) = 24/5

  z = 4 4/5

____

17. The acute angles are complementary:

  x = 90 -40 = 50

__

From the Pythagorean theorem:

  y = √(15² -9.6²) = √132.84

  y ≈ 11.5

In the diagram, line x|| line y. Find the angle measures below.
Yanka [14]

Answer:

<1 = 95

<2 =85

Step-by-step explanation:

<1 = 95

They are alternate exterior angles and alternate exterior angles are equal when the lines are parallel

<1 + <2 = 180  since they form a straight line

95+ <2 =190

Subtract 95 from each side

95-95+<2 =180-95

<2 =85
