Question

triangle PQR is an insoseles triangle with PQ=PR if < R=42°,find the measure ment of <P​

Answer 1

Answer:

96°.........................

Answer 2

Answer:

96°

In a ∆PQR shown in above figure

PQ=PR

SO, <Q = <R = 42° (given in question)

Now, we know that

In a ∆ sum of all angle is 180°

<P + <Q + <R = 180°

<P + 42° + 42° = 180°

<P = 180° - 84° = 96° ANS
