Question

In ∆PQR; LP=30° PQ=PR Then find measurement of angleQ & angleR​

Answer 1

Step-by-step explanation:

P=30°, PQ=PR then angle R and angle Q are equal R=Q=X

so, P+Q+R=180

2X=180-30

=150

X =150/2

X=75

P=Q=75

Answer 2

Answer:

Given<p=30,PQ=PR

by the property of triangle that is the angles opposite to the equal sides are equal

   we have <Q=<R

we know that the sum of the angles of a triangle=180

Here let <Q=<R=x

<P+<Q+<R=180

30+x+x=180

30+2x=180

2x=180-30

2x=150

x=150/2

x=75

<Q=<R=75
