Question

In a triangleABC, if A=75degree and B=45degree then what is the value of b+2c

Answer 1

Answer:

165

Step-by-step explanation:

A+B+C=180

C=60

b+2c=45+120

=165

Answer 2

Step-by-step explanation:

in ∆ABC

A=75° B=45°

to find b+2c

by angle sum property

A+B+C=180°

75+45+C=180°

120°+C=180°

C=180°-120°

c=60°

b+2c

45°+2(60)°

45°+120°

165°
