Answer:
<em>y</em> = 6
Step-by-step explanation:
The red square represents a 90 degree angle. If you subtract 36 from 90 you will get 54. Then to find <em>y</em>, divide 54 by 9 and you get 6.
Hope this helped!! :)
∠3 = 22°
∠4 = 22°
∠5 = 88°
86 + 72 = 158
180 - 158 = 22
∠3 ≅∠4 they're verticle angles
22+ 70 = 92
180 - 92 = 88
