Question

in triangle abc, BC is produced to D if angle ABCD is equals to 110 degree and angle abc is equals to 70 degree find angle BAC

Answer 1

Given angle ACD is equal to 110 degrees and angle abc is equal to 70

According to problem

Acd=abc+bac

110=70+bac

Bac=110-70

=40

Answer 2

Answer:

The value of angle BAC is 40

Step-by-step explanation:

Step 1:

Given Data: Triangle ABC, BC is produced to D

Angle ABCD =110 degree

Angle ABC = 70 degree

To calculate the angle of BAC:

Step 2:

Given angle ACD is equal to 110 degrees and angle abc is equal to 70  

According to problem  

ACD=ABC+BAC

110=70+BAC

BAC =110-70(Subtract ACD and BAC)

=40

The value of BAC is 40
