Answer:
B. 50°
Step-by-step explanation:
Use the tangent ratio, then use the inverse to find the angle of elevation, X°
A pair of angles with a common vertex and sides that are opposite rays
2x + 14 = 4x - 6
14 = 2x - 6
20 = 2x
10 = x
a) 14 + 6 = 2x
20 = 2x
10 = x
b) -2x = 20
x = -10
c) 2x - 4x = -20
-2x = -20
x = 10
d) x = 10
b is the only one that doesn’t equal 10.
