Answer:
the unknown angle is 88°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the opposite interior angles. Therefore, in the tall triangle, 60 + 40 = 100, meaning the bottom left angle in the small triangle is 100-64=36. And b/c angle sum of a triangle is 180°, 180-36-56=88°

y = - 3
the equation of a horizontal line, parallel to the x- axis is y = c where c is the value of the y- coordinate the line passes through
Line passes through ( - 7, - 3) → y- coordinate is - 3
equation of line is y = - 3
