Answer:

y = 14

Explanation:

Since AC = BC then the triangle is isosceles and the base angles are congruent, that is

∠A = ∠B = 50°, thus

∠C = 180 - (50 + 50) ← sum of angles in Δ = 180°

= 180 - 100 = 80°, hence

5y + 10 = 80 ( subtract 10 from both sides )

5y = 70 ( divide both sides by 5 )

y = 14

To find the value for y in the equation y = 9 + 3x, substitute a specific value for x into the equation and solve for y.

The value for y in the equation y = 9 + 3x depends on the value of x.

To find the value of y, you need to substitute a specific value for x into the equation and then solve for y.

For example, if x = 2, the value of y can be found by substituting x = 2 into the equation:

y = 9 + 3(2)

y = 9 + 6

y = 15

So when x = 2, y is equal to 15.
