Answer:
x = 4
Step-by-step explanation:
(6x - 3)° = (2x + 13)° are vertical angles that equal each other get x by itself and solve for x.
(6x - 3)° = (2x + 13)°
6x - 2x = 13 + 3
4x = 16
x = 4
Substitute x for the angles.
(6x - 3)° = ?
(6*4 - 3)° = ?
(24 - 3)° = 21°
(2x + 13)° = ?
(2*4 + 13)° = ?
(8 + 13)° = 21°
Answer:
cos(C)
Step-by-step explanation:
Recall that the sine ratio is opposite over hypotenuse.

Also the cosine ratio is adjacent over hypotenuse.

The tangent ratio does not come close because it doesn't involve the Hypotenuse.

Answer:
132°
Step-by-step explanation:

therefore x = 132°
