Question

4. APQR is isosceles with PQ = PR. If ZQ = 40°, find all the angles of the triangle​

Answer 1

Answer:

if pq=pr

and if pq= 40 degrees

pr is also equal to 40 degrees (given)

Hence

RQ= 180-40-40

RQ= 180-80

RQ=100

Answer 2

P = 100 degrees

Q = 40 degrees

R = 40 degrees

Step-by-step explanation:

Given,

Angle Q = 40degrees

PQ = PR

So, the angle Q and angle R are equal because angles opposite to equal sides are equal.

Angle R = 40 degrees

In a triangle, sum of all sides = 180degrees

Hence, Angle P = 180 - R - Q

= 180 - 40 - 40

P = 100degrees
