Question

In Triangle ABC, if angle A is 45 degrees, and angle B is 55 degrees, how big would angle C have to be?

Answer 1

Answer:

85

Step-by-step explanation:

In triangle ABC

A+B +C =180

A+45+55=180

A=180-100

A=80

AO is the bisector of angle A

then x=y=40

in triangleAOB

x+B+AOB=180

40+45+AOB=180

AOB=95

Similarly in triangleAOC

y+C+AOC=180

40+55+AOC=180

AOC=85
