Question

Solve for the letter y in algebraic form

Answer 1

y = 14

Explanation:

The angle of a straight line is 180°.

So both of these angles make up 180°.

The equation used in these problem is: a + b = 180°

Substitute the values to the equation.

(11y - 12) + (2y + 10) = 180

11y - 12 + 2y + 10 = 180

11y + 2y - 12 + 10 = 180

13y - 12 + 10 = 180

13y - 2 = 180

13y = 180 + 2

13y = 182

y = 182 ÷ 13

y = 14

Hope this helps!

Answer 2

y = 14°

Explanation:

(11y -12)° + (2y + 10)° = 180°

11y + 2y -12 + 10 = 180°

13y - 2 = 180°

13y = 182°

y = 182/13 = 14°
