Answer:

a. x = 12

b. x = 4

Step-by-step explanation:

a. RECTANGLE

ABCD is a rectangle, AC and BD are its diagonals.

Diagonals of a rectangle are congruent.

Therefore,

AC = BD

10x + 8 = 9x + 20

10x - 9x = 20 - 8

x = 12

b. RHOMBUS

Diagonal of a rectangle bisect opposite angles.

Therefore,

(5x + 3)° = (2x + 15)°

5x + 3 = 2x + 15

5x - 2x = 15 - 3

3x = 12

x = 12/3

x = 4

Which of the following theorems verifies that XYZ - UWV

Rzqust [24]

Answer:

I think it's AA because the sum of a triangle is 180 and if you subtract the right angle and the other angle from 180 it gives you the same angle in the other triangle.

Step-by-step explanation:

180-(90+70)=20 The other angle in the first triangle

180-(90+20)=70 The other angle in the second triangle

These angles show that they're similar
