In Fig. 6.35, QP || RT. Find the values of x and y.
Solution:
Given, PQR is a triangle.
Also, QP || RT
We have to find the values of x and y.
Since QP || RT, the alternate interior angles are equal.
So, ∠QPR = ∠PRT
x = 70°
Angle sum property of a triangle states that the sum of all three interior angles of a triangle is always equal to 180 degrees.
∠P + ∠Q + ∠R = 180°
x + 30° + y = 180°
70° + 30° + y = 180°
100° + y = 180°
y = 180° - 100°
y = 80°
Therefore, the values of x and y are 70° and 80°.
