The picture below shows a parallelogram-shaped bookshelf Aaron bought for his wall. He rotates the shelf 90° clockwise and then 180° counterclockwise to decide how to arrange it on the wall. Which of the following statements is true about this shelf after Aaron rotates it?

A) The measure of angle Q would be 70°

B) The measure of angle R would be 70°

C) The measure of angle S would be 110°

D) The measure of angle P would be 140°​

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
