Question

In PQR, ∆P=60°,∆Q=75°then ∆R will be
​

Answer 1

Step-by-step explanation:

Solution:-

$\begin{gathered}\begin{gathered}\bf Given \begin{cases}\text{Angle(p) =60⁰} \\ \text{Angle (q) = 75⁰} \\ \text{Angle(r)=45⁰}\end{cases}\end{gathered}\end{gathered}$

$180 - (60 + 75) \\ 180 - 135 = 45$
