Question

1) In ∆ABC, if ∠A + ∠B = 108° and ∠B + ∠C = 130°, find ∠A, ∠B and ∠C. 2) In ∆PQR, if ∠P − ∠Q = 42° and ∠Q − ∠R = 21°, find ∠P, ∠Q and ∠R.

Answer 1

Answer:

<A=50°<B=58°<C=72°

<P=95°<Q=53°<R=32°

Step-by-step explanation:

1) <A+<B=108°

<B+<C=130°

By solving this Equation, we get <A=50° <B=58° <C=72°

2) <P-<Q= 42°

<Q-<R= 21°

By solving this Equation ,we get

<P= 95° <Q=53° <R=32°

Answer 2

Answer:

here's your answer mate

<P = 95°

<Q = 53°

<R = 32° ...

hope it correct to u...
