Answer:

84.5

Step-by-step explanation:

Use trig functions to find x. Trig functions are special relationships which exits between the sides of right triangles. Since you need to find x the hypotenuse and you have the adjacent side to 77 degree angle use cosine.

Cos 77 = 19/x

0.22495 = 19/x

19/0.22495 = x

84.5 = x

Answer:

#18)  <em>m</em>∠B = 107°

#19) <em>m</em>∠B = 17°

Step-by-step explanation:

*Supplementary angles are angles who's measures equal 180°

*Complementary angles are angles who's measures equal 90°

#18) If ∠A is 73°, then we must subtract 73 from 180.

180 - 73 = 107

This means that <em>m</em>∠B = 107°.

#19) If ∠A is 73°, then we must subtract 73 from 90.

90 - 73 = 17

This means that <em>m</em>∠B = 17°.
