The two unknown sides are equal to each other so then the two unknown angles are also equal.
A triangle angles add up to 180
36 + 2x = 180
2x = 180 - 36
2x = 144
unknown angles x = 72°
draw line down center of triangle to make two right triangles with side 22/2 = 11. SOH CAH TOA
cos(72) = 11/H
H = 11/cos(72)
H = 35.6
perimeter = 22 + 2(35.6)
perimeter = 93.2 cm

Answer:
Step-by-step explanation:
0.9*2b = 1.8b
0.9*-1 = -0.9
So far we have 1.8b-0.9. It can't be simplified further.
Then, we add the 2nd part, -0.5b+1.
We have:
1.8b-0.9-0.5b+1. Next we combine like terms.
1.8b-0.5b = 1.3b.
-0.9+1 = 0.1
Then we put it together.
1.3b+0.1 is our answer.
Hope this helped! Have a nice day :D
10/18 because 18-8=10 and the total amount is 18 so the fraction is 10/18
The answer to your question is choice C.
