The sum of the interior angles in a triangle = 180

There are three angles, 30, x, and x.
Since there are two x, you can therefore write this equation and solve for x.

180 = 2x + 30
150 = 2x
/2 /2
75 = x

Therefore the answer is C, 75.

Well since both of the angles are congruent we just need to do 180 - 30 = 150
150 / 2 = 75

(C) is the answer :D

Triangle Q M N is shown. The length of Q M is 18, the length of M N is 17, and the length of Q N is 20. Law of cosines: a2 = b2

Answer:

53°

Step-by-step explanation:

17² = 18² + 20² - 2(18)(20) cos Q

289 = 324 + 400 - 720 cos Q

289 = 724 - 720 cos Q

-435 = -720 cos Q

0.6042 = cos Q

$cos^{-1} (0.6042) = Q$

Q = 52.83
