Question

if∆abc~∆pqr and m angle a=45°, m angle q=87°, then m angle c= -----.​

Answer 1

$given$

angle A = 45°

angle B = 87°

$to \: find$

find angle C

$solution$

As we know sum of all angle of a triangle is 360°.

therefore,

a+b+c = 360°

45°+87°+c = 360°

132°+c = 360°

c = 360°-132°

c = 228°
