Answer:
∠A = 90
∠B = 30
∠C = 60
Step-by-step explanation:
Let ∠B = x
∠A = 3x
∠C = x + 30
Angle sum property of triangle: Sum of three angles of triangle is 180
x + 3x + x + 30 = 180 {Combine like terms}
5x + 30 = 180
5x = 180 - 30
5x = 150
x = 130/5
x = 30
∠A = 3*30 = 90
∠C = 30 + 30 = 60
Answer:
y^(-5/4)
Step-by-step explanation:
because
1/ (y^(5/4) = (1/y) ^(5/4) = y^(-5/4)
The sum of everything is 720 degrees, because of the six sides in this figure.
We sum all angles and get 595
720 - 595 = 125
The answer is 125 degrees
Answer:
I believe its 57.
Step-by-step explanation:
180-66=57.
57+57+66=180
