Question

In the given figure if line segments PQ and RS intersect at point T, such that ∠PRT=40°, ∠RPT=95° and ∠TSQ=75°, find ∠SQT.

Answer 1

Here is your answer
And the reason of both equations are same as the sum of two angle of triangle is equals to the exterior angle.

Answer 2

Hello mate ☺

____________________________

Solution:

In ∆PRT, we have

∠PRT+∠RPT+∠RTP=180°   (Sum of three angles of a triangle =180°)

⇒40°+95°+∠RTP=180°

⇒∠RTP=180°−40°−95°=45°

∠RTP=∠QTS     (Vertically Opposite Angles)

Therefore, ∠QTS is also equal to 45°

In ∆STQ, we have

∠SQT+∠TSQ+∠QTS=180°  (Sum of three angles of a triangle =180°)

⇒∠SQT+75°+45°=180°

⇒∠SQT=180°−75°−45°=60°

I hope, this will help you.☺

Thank you______❤
