Answer:
x = 3
Step-by-step 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
Hope this helps :)
Have a nice day!
x=3
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.
