Which of the following shows the equation log subscript 4 baseline (x + 6) = 2 rewritten using logarithms?

C

Step-by-step explanation:

A. False.

The equation is equivalent to the equation

The right side is not

B. False.

The equation is equivalent to the equation

The right side is not

C. True.

Since then the equation is equivalent to the equation

D. False.

Since this option is false

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
