Answer:
80
Step-by-step explanation:
because there has to be a right triangle(90) and if a angle is 10 you add =100 that then subtract from 180 =80
80 degrees
Do 90 plus 10.
The do 180 minus 100
because a triangle adds up to 180
169.50
-1 =v
3 = -2v − v
Combine like terms
3 = -3v
Divide each side by -3
3/-3 = -3v/-3
∠TUS I'm pretty sure because t and u make a right angle
