Question

in angle pqr angle p=3 q and r=2 angle q.find the angles of angle pqr​

Answer 1

Answer:

Given

∠P=2∠Q.......(1) and 

∠R=23∠Q........(2)

Also sum of angles of a triangle is 180 degree.

From equation (1) and (2):

⟹∠P+∠Q+∠R=180o

⟹2∠Q+(3/2)∠Q+∠Q =1 80o

⟹∠Q = 9180o × 2 = 40o.

1. So ∠P=2 (40o) = 80o and ∠R= (3/2) 20o = 60o

Answer 2

Answer:

<p=90° , <q=30°, <r=60°

Step-by-step explanation:

<p= <3q

<r= <2q

<p+<q+<r=180°

<3q+<q+<2q=180°

<6q=180°

<q=180°/6

<q=30°

<p=<3q=3*30°

=90°

<r= <2q=2*30°

=60°
