Question

In △PQR, ∠P=80° and ∠Q=40°. Therefore, ∠R=______. *​

Answer 1

Answer:

add me as brainlist??? plz ;)

Step-by-step explanation:

40∘ Hence, the measure of each angle is 80∘, 60∘ and 40∘respectively. ... Let us suppose the angles of a ∆PQR such that ∠P < ∠Q < ∠R. A.T.Q, ∠Q = 2∠ ... 6∠P = 180∘ ⇒ ∠P = 30∘ Therefore, ∠P = 30∘ ∠R = 60∘ ∠R = 90∘ Hence, the ... z = 40∘ Now, In △NEM ∠N + ∠E + ∠M = 180∘ (Angle sum property)

Answer 2

Answer:

R= 60°

Step-by-step explanation:

All sides of triangle sum up to 180°

Given:

ΔPQR

P=80° , Q= 40° , R= 180-(80+40)

=180-120

=60°
