Question

Pls ans this fast ..............

Answer 1

if cosA= cosB then PQ/PB=MN/MA AND ANGLE P=ANGLE M



SO TRIANGLE ARE SIMILAR BY SAS RULE OF SIMILARITY





THEREFORE ANGLE A=ANGLE B

Answer 2

hlo

In triangle AMN and triangle BPQ

Cos A = Cos B

AM÷ AN = BP ÷ BQ

Sides are equal

BQ = AN

BP = AM

PQ = NM

AM = BP , AN = BQ

angles opposite to equal sides are equal

Angle A = Angle B
