Question

Square PQRS is a cylic quadrilateral m angel P /=60 degrees, hence m angel R = _____ degrees​

Answer 1

Answer:

120°

Step-by-step explanation:

Given,

m∠P=60°

In a cyclic quadrilateral the sum of two opposite angles is equal to 180 degrees (supplementary angles)

m∠P is opposite to m∠R

so, m∠P + m∠R = 180°

60° + m∠R = 180°

m∠R = 180°-60°

m∠R=120°
