Answer:
Step-by-step explanation:
The marks on both sides of the triangle shows that the sides are equal. This means that the triangle is an isosceles triangle.
This means that
x = 4
Also, in an isosceles triangle, the base angles are equal. Therefore, the sum of the base angles would be 2y.
The sum of angles in a triangle is 180 degrees. Therefore,
2y + 50 = 180
Subtracting 50 from both sides of the equation, it becomes
2y + 50 - 50 = 180 - 50 = 130
2y = 130
y = 130/2 = 65 degrees.

Answer:
The slope of the line is 6.
Step-by-step explanation:
Two points on the line are (1,5) and (-1,-7)
y1 - y2 / x1 - x2
-7-5/-1-1 = -12/-2 = 6
