Question

find the value of x, also find angle a b and c​

Answer 1

Step-by-step explanation:

Sum of the angle of the triangle = 180°

5x-60° + 3x-80° + 2x+40° = 180°

10x - 100° = 180°

10x = 180°+100°

10x = 280°

x = 28°

5x-60° = 140-60 = 80°

2x+40 = 56+40 = 96°

3x-80° = 84-80 = 4°

Answer 2

Step-by-step explanation:

WE KNOW THAT SUM OF ALL ANGLES IN A TRIANGLE = 180°

SO

<A+<B+<C=180°

5x-60+2x+40+3x-80=180

10x-100=180

10x=180+100

10x=280

x=280/10

x=28

THEREFORE X=28

Now

A=5x-60

=5×28-60

=80°

B=2x+40

=2×28+40

=96°

C=3x-80

=3×28-80

=4°

THERE FORE THE ANGLES ARE 80°,96°,4°

I MAY BE WRONG IN WHICH SIDE IS A AND B BECUASE IN THIS PICTURE WHICH IS A AND WHICH IS B IS NOT GIVEN.
