Question

PLEASE HELP PLEASE & THANK YOU !!!

Answer 1

x=3

Explanation:

In a rhombus, 2 opposite angles have to be the same. So (8x-3)+(5x+6)=2(3x+12). X=3. So one angle is: 8(3)-3=24-3=21. 21+90=111 and so half of x=180-111=69. So angle x=69x2=138.

Answer 2

x = 3

Explanation:

WXY is isosceles, so <XWY = <XYW.

Substitute the angle values

8x - 3 = 3x + 12

Add 3 on both sides and minus 3x on both sides

5x = 15

Divide by 5 on both sides to isolate x

x = 3

Hope this helps :)

Have a nice day!
