Find the measure of each angle

m∠QRT = 47°

m∠TRS = 133°

Step-by-step explanation:

Because points Q, R, and S are collinear, ∠QRT and ∠TRS are supplementary. This means that:

m∠QRT + m∠TRS = 180°

Plug-in the known values and simplify:

3x + 5 + 10x - 7 = 180

13x - 2 = 180

13x = 182

x = 14

Now that you have the value of x, plug them into the values of the angles:

m∠QRT = 3x+ 5

              = 3(14) + 5

              = 42 + 5

              = 47°

m∠TRS = 10x - 7

             = 10(14) - 7

             = 140 - 7

             = 133°

To double-check:

133° + 47° = 180°     ☺
