To find the value of x, we can use the fact that the sum of the angles in a triangle is 180 degrees.
Given that ∠SRT = ∠STR and m∠SRT = 20, we know that m∠STR = 20 as well.
Therefore, m∠STR + m∠SRT + m∠SRU = 180
20 + 20 + 4x = 180
40 + 4x = 180
4x = 140
x = 35
Therefore, the value of x is 35.
Find the vaule of x
∠SRT = ∠STR, m ∠SRT =20, m ∠ SRU =4x
