Answer:
y = 25
Step-by-step explanation:
Given that,
m∠PTQ = 3y –10 and m∠QTR = y
We need to find the value of y so that ∠PTR is a right angle.
For a right angle, one of the angle is 90 degrees. The sum of the angle of a triangle is equal to 180 degrees. So,
3y –10 + y + 90 = 180
Taking like terms together
3y+y = 180 -90 +10
4y = 100
y = 25
So, the value of y is 25.
Answer:
