Question

In △PQR, if the measures of ∠Q and ∠R are 100° and 45°respectively, find the measure of ∠P

Answer 1

➸ Given:-

In ∆PQR

• ∠Q = 100°
• ∠R = 45°

☣ To Find:-

• Measure of ∠P.

☢ Solution:-

WKT

Sum of Angles in a ∆le is 180°

$→\;\sf{∠P+∠Q+∠R = 180°}$

$→\;\sf{∠P+100°+45° = 180°}$

$→\;\sf{∠P = 180°-145°}$

$→\;\sf{∠P = 35°}$

Required Value

• ▣ $→\;\Large\red{\bold{35°}}$
