Point Q is equidistant from the sides of ∠TSR. Find m∠RST.

A:20°

B:10°

C:50°

D:25°

angle RST = C) 50 degrees

Step-by-step explanation:

angle TSQ and angle QSR are the same angle so plug them equal to each other finding x

2x+5 = 5x-25

minus 2x by both sides --> 5 = 3x - 25

add 25 to both sides --> 30 = 3x

now divide both sides by 3 getting x alone --> x = 10

now plug that back in to both equations to get the angles and add them together

25 + 25 = 50
