Find the value of x.
castortr0y [4]

Answer: x= 19


Step-by-step explanation:

RS =~ ST presumably reads segment RS is congruent to segment ST, i.e. the same length.

Then the triangle is isosceles, and angle SRT = angle STR. Angle STU = 180-angle STR.


SRT = 3x - 48, STU = 9x, so STR = 180-9x

SRT = STR

3x - 48 = 180 - 9x

3x + 9x = 180 + 48

12x = 228

x = 19
