1.	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» 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

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
