PLEASE ANSWER TODAY ASAP WILL GIVE BRAINLIEST FOR FIRST CORRECT ANSWER. Angle a and angle b are complementary angles. The measure of ∠a is 42°.

Which equation represents this situation with x representing the measure of ∠b?

42−x=90

90+x=42

42+x=90

90+42=x

42+x=90

Step-by-step explanation:

Complementary angles are when their measures add up to 90°

Therefore, if angle a is 42° you would find angle b by subtracting 42° from 90° which is shown in equation number three.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

correct me if i'm wrong and if it is i'm truly sorry.
