Answer:
this angle is a right angle(90°)
and one of the 2 angles is 30
3x+30=90
3x=90-30
3x=60
x=20
==> B
Answer:
a
Step-by-step explanation:
52 = (2*W - 5) * W
52 = 2*W^2 - 5*W
0 = 2*W^2 - 5*W - 52
0 = (2W - 13)*(W + 4)
2W - 13 = 0 or W + 4 = 0
W = 13/2 or W = -4
Width cannot be negative so discard W = -4
W = 13/2 L = 2*(13/2) - 5 = 13 - 5 = 8
