Question

in ∆ PQR ,angle P= 50, angle Q =60 then find angle R ​

Answer 1

Step-by-step explanation:

angle P+angle Q+angle R=180⁰(Linear Pair)

50⁰+60⁰+angle R=180⁰

110⁰+angle R=180⁰

angle R=180⁰-110⁰

angle R=70⁰

Answer 2

Hi ⭐♥️❣️

In a triangle sum of all angles is 180°

$p + q + r = 180 \\ 50 \degree + 60 \degree + r = 180 \degree \\ r = 70 \degree$
