Since Line RS is congruent to Line ST, it means that Line RT is the base of an isosceles triangle with vertex angles at R and T. Therefore, m∠RST = m∠RTS.
We can set up an equation with this information:
8x - 60 = 10x
Solving for x:
-60 = 2x
x = -30
Therefore, the value of x is -30.
Find the value of x. Given: Line RS≅ Line ST, m∠RST =8x−60, m∠STU=10x
image shows a triangle with vertexes, s r t and a continuous base line that is u.
