In a certain triangle, the measure of angle a is three times as big as the measure of angle c and the measure of angle b is 130 degrees bigger than the measure of angle c. what is the degree measure of angle c?

C=10 degrees

Step-by-step explanation:

1. C=x

x=unknown

We do not know the value of x, we also do not know the value of c.

you can use c, but i feel like x will be less confusing

A=3x

B=x+160

all angles in a triangle add up to 180.

x+3x+x+130=180

5x=50

x=10 degrees

hope this helped

the answer is d

step-by-step explanation:

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
