Answer:

x = 33.8°

Step-by-step explanation:

The resulting diagram we have is a right triangle. To find x, apply trigonometric function.

Reference angle = x

Opposite = 116

Adjacent = 173

Apply TOA:

Tan x = Opp/Adj

tan (x) = \frac{116}{173}

x = tan^{-1}(\frac{116}{173})

x = tan^{-1}(\frac{116}{173})

x = 33.8° (nearest tenth)

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 :)
