et mA = 40°. If B is a complement of A, and C is a supplement of B, find these measures. mB = ° mC = °
Free_Kalibri [48]

Alright, lets get started.

We have given angle A = 40°

We are also given angle B is complement of A.

Complementary angles are two angles whose sum is 90, it means

angle B = 90- A

angle B = 90 - 40

angle B = 50° Answer

Now given, angle C is supplement of angle B.

Supplementary angles are two angles whose sum is 180°.

Means angle C = 180 - B

angle C = 180 - 50

angle C = 130° : Answer

Means angle B = 50° and angle C = 130°

Hope it will help :)

Find f(-4) for f(x)=9(3)^x
jeka94

Answer:

f(-4) = \dfrac{1}{9}

Step-by-step explanation:

f(x) = 9(3)^x

f(-4) = 9(3)^{-4}

f(-4) = 3^2 \cdot 3^{-4}

f(-4) = 3^{-2}

f(-4) = \dfrac{1}{9}
