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.
Let x be the first of the four consecutive numbers.
Then x+1 is the second,
and x+2 is the third,
and x+3 is the fourth.
If their sum is 810, then
x + x+1 + x+2 + x+3 = 810
If you solve that equation for x, you'll have the answer to your question.
Answer:
x equals 3
(-2, -3) and (8, -3) the middle of the x coordinate is 3
