M<STR = 180 - 8x degrees also m < SRT = 180-8x ( because side RS = side ST, so isosceles triangle) So 7x - 54 + 180 - 8x = 8x (ext. angle of triangle =sum of opposite internal angles) 7x - 8x - 8x = -180 + 54 = -126 -9x = -126 x = 14 answer
The sum of the measures of the angles of a triangle is 180 degrees. Angles STU and STR are supplementary angles. Angles R and STR are congruent. m<STU + m<STR = 180 8x + m<STR = 180 m<STR = 180 - 8x m<R = m<STR = 180 - 8x m<RST + m<R + m<STR = 180 7x - 54 + 180 - 8x + 180 - 8x = 180 -9x + 360 = 180 -9x = -126 x = 14
