Question

angleOTR=21°
find angleQPR​

Answer 1

Answer:

I don't know if I say you ut

Answer 2

Answer:

Step-by-step explanation:

from the diagram,we can understand that PQ and TR are parallel lines

x=<QTR=25°(as they are alternate interior angles)

so <TQR=x=25°(given in the question)

so <PQR=25+25=50°

<QPR=<PRT=y(alternate interior angles)

<PRQ=180-2y(linear pair)

so considering the ΔPQR,

<PQR+<PRQ+<QPR=180°(sum of the interior angles in a triangle is 180°)

50°+ 180-2y + y=180°⇒y=50°

we have got <QPR=y

so <QPR=50°

hope this helps you
