Question

Angles Q and R of ∆PQR are 25° and 65°. Write which of the following is true.

a) PQ² + QR² = RP².
b) PQ² + RP² = QR².
c) RP² + QR² = PQ².

*GIVE THE ANSWER WITH EXPLANATION*

Answer 1

Answer:

angle Q=25°

angle R=65°

so angle P={180-(25+65)}°=(180-90)°=90°

so , it is a right angle triangle

here hypotenuse=QR

so ,PQ^2+PR^2=QR^2

so, (b) is the correct answer
