Step-by-step explanation:
a/q both the traingles are similar/congruent so,
theri angles also have equal value
angle Q = angle A
so,
apply angle sum property of triangle in ∆PQR
so according to it
Angle
P + Q + R = 180
→ 45° + 15° + Q = 180
→ 60° + Q = 180
→ Q = 180 - 60 = 60°
→ angle Q = 60°
therefore, angle A = 60°
Angle R = angle B
so,
angle B = 15°
as, angle P = angle C
so,
angle C = 45°
hope this answer helps you dear....take care and may u have a great day ahead!
