Answer:
Step-by-step explanation:
If one angle = 90 degrees, then the other 2 added together must also = 90.
There is only 1 answer to this, since the triangle is isosceles..
x + x = 90 Combine
2x = 90 Divide by 2
x = 90/2
x = 45
So both acute angles = 45 degrees.

Answer:
8c - 7r + 10p - 20e
Step-by-step explanation:
Subtract (20c + 15r + 75p + 50e) - (12c + 22r + 65p + 70e)
(20c + 15r + 75p + 50e) - (12c + 22r + 65p + 70e)
Open bracket
20c + 15r + 75p + 50e - 12c - 22r - 65p - 70e
Collect like terms
= 20c - 12c + 15r - 22r + 75p - 65p + 50e - 70e
= 8c - 7r + 10p - 20e
