Answer: A. 55°
Step-by-step explanation:
Area of a triangle is given by 1/2bh where b is the base and h is the perpendicular height of the triangle.
The area is 80x∧5y³ and the height is x∧4y
Thus; 80x∧5y³ = 1/2(x∧4y) b
160x∧5y³ = (x∧4y)b
b = (160x∧5y³)/ x∧4y)
b = 160xy²
Therefore, the base of the triangle is 160xy²
I know, you have to divide 90 by what ever the length is, then you have to figure out where the points are. So it should be.... D!!!
= 10 hole minus. U add the two halfs then ad the hole minus
