Step-by-step explanation:
It’s right
Answer:
Step-by-step explanation:
Straight angle is equal to 180°
Angle x, 60° and 80° form a straight angle.
<u>Then we have following equation to solve for x:</u>
- x + 60° + 80° = 180°
- x + 140° = 180°
- x = 180° - 140°
- x = 40°
Cosine is .
Apply the equation:
B is the adjacent side so
cosine is:
Cos(t) = 5/2
