Question

Please Answer This figure

Answer 1

Answer:

1)7x+6x=130[By exterior angle property of a triangle]

=>13x=130

=>x=130/13

=> x=10

2)Angle BAC=7x

=7×10

=70

3)Angle ACB=6x

=6×10

=60

Answer 2

angle ABC=(180-130)°

=50°

ATQ,

angleA plus angle B plus angleC= 180°

7x plus 6x plus 50°=180°

13x=130°

x=10°(i)

angle BAC= 10×7

=70°

angleACB=10×6

=60°
