Find X. Round to the nearest tenth. Law of Cosines : c2 = 22 + b2 - 2ab cos C

fiasKO [112]

Answer:

70.5°

Step-by-step explanation:

22² = (20)²+(18)² - 2(20)(18) cos X

484 = 400 + 324 - 720 cos X

-240 = -720 cosx

1/3 = cos X

$cos^{-1}(\frac{1}{3})$ = X

X = 70.52877937

Two angles are supplementary. The measure of one angle is 4 more than 7 times the other angle. Find the measures of both angles.

mylen [45]

Answer:

The smaller angle measures 44° and the larger measures 136°

Step-by-step explanation:

Smaller angle = x

Larger angle = 3x + 4

Therefore, we have:

x + 3x + 4 = 180

4x = 180 - 4

4x = 176

x = 176/4

x = 44 ⇒ 3x + 4 = 136

The smaller angle measures 44° and the larger measures 136°
