The sum of two angles is 138.6°. One angle has a measure of 54°. What is m, the measure in degrees of the second angle?

84.6

Step-by-step explanation:

All u gotta do is 138.6 - 54

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
