Answer» Answer: ANGLE Q = angle r = 75° Step-by-step explanation: ∆pqr as, pq = pr therefore, angle q = angle r ( opp.ANGLES to equal opp. SIDES are also equal ) sum of angles of a triangle = 180° therefore, angle p + angle q + angle r = 180° 30° + x + x = 180° 30° + 2x = 180° 2x = 180° - 30° 2x = 150° x = 150° / 2 x = 75° that's your answer

Answer»

Answer:

ANGLE Q = angle r = 75°

Step-by-step explanation:

∆pqr

as, pq = pr

therefore,

angle q = angle r

( opp.ANGLES to equal opp. SIDES are also equal )

sum of angles of a triangle = 180°

therefore,

angle p + angle q + angle r = 180°

30° + x + x = 180°

30° + 2x = 180°

2x = 180° - 30°

2x = 150°

x = 150° / 2

x = 75°

that's your answer
