Let x be the measure of the angle. The mathematical equation of the problem is
5(90-x) =

(180-x)

°
Answer:
KQ = bk/2kq
Kq = 25/2 = 12.5
Step-by-step explanation:
Hope this helps!
H^2=x^2+y^2 (Pythagorean Theorem)
75^2=18^2+y^2
y^2=75^2-18^2
y^2=5625-324
y=√5301
y≈72.8
Terrible picture, lacking the requisite "not to scale."
Angle EAN is the sum of angles 1,4 and 6
EAN = 57 + 85 + 12 = 154
Choice B
