Two angles are complementary. (what does complementary mean?) The larger angle is twice as large as the smaller angle. What is the measure of the smaller angle? A) 30°
B) 60°
C) 90°
D) 120°

A) 30°

Step-by-step explanation:

What is complementary?

Complementary means they add up to 90 as the supplement is adding up to 180. Look at it like this, complementary additions to diets provide the needed nutrients while being the main thing, however, it is the lesser value because its included as a part of the meal. A supplement is a replacement of what you dont get and as a result its a larger, part in getting your dietary needs met outside of the meal itself.

So with complementary being equal to 90 degrees we'd solve the "The larger angle is twice as large as the smaller angle. What is the measure of the smaller angle?" by giving an equation

Our smaller angle is represented by x

Complimentary means the two angles add up to 90, x is the smaller angle and the larger one is two times that (2x) when added together equal 90

x + 2x = 90

     3x = 90

       x = 30

The smaller angle is 30

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours
