Answer:
D
Step-by-step explanation:
X is 21
z is the same as 111
y is 48
Number of sides= 10
Side length= 4.6 ( or in this case base)
161 sq inches / 10 = 16.1 area of triangle.
Area of triangle =(b<span>ase * </span>height)/2
16.1=(4.6*h)/2
multiply 16.1 by 2 (cancels the dividing the 2)
32.2=4.6*h
divid 32.2 by 4.6
<span>7 is the height of the triangle</span>
