Question

In a APQR, the sides have been produced as shown. If
21 = 350, Z2 = 75°, find the third angle of the triangle.
Also, find ZXPZ + ZPQY + ZQRZ.​

Answer 1

Answer:

1. third angle =180-(75+35)

=70(using angle sum prop in trianglePQR 2.WEknow that the sum of exterior angle of any triangle is always360 so, no.2 ans=360

Answer 2

Answer:

angle 1=35°

angle 2=75°

according to angle-sum property of a triangle

angle 1 +angle 2+angle 3=180°

35°+75°+angle 3=180°

110°+angle 3=180°

angle 3 = 180°-110°

angle 3= 70°
