Question

In quadrilateral QRST, angle rst measures (5x + 15)o. Angle TQR measures (4x + 3)o.

What is the measure of angle RST?

Answer 1

c: 105°

edge 2022

Answer 2

2(5x + 15) + 2(4x + 3) = 360
10x + 30 + 8x + 6 = 360
18x = 324
x = 18

so

RST = 5x + 15 = 5(18) + 15 = 105

answer

RST = 105 degree
