Answer:Since the expression on each side of the equation has the same denominator, the numerators must be equal.

Take the square root of both sides of the equation to eliminate the exponent on the left side.

F(-7) = (-7)^2 + 6 = 49 + 6 = 55;
( g o f)(-7) = g(f(-7)) = g(55) = (55 + 8)/5 = 63/5;

What is the measure of m<3 A. 58 degrees B. 122 degrees C. 116 degrees D. 64 degrees

Firdavs [7]

Hello!

$\large\boxed{\text{ D. 64 degrees}}$

Angles in a triangle sum up to 180°, so:

180° = 58° + 58° + m∠3

Combine and subtract:

180° = 116° + m∠3

64° = m∠3

Thus, the answer is D.
