Please help! I will give brainiest to the first right answer WITH STEPS!!! If it's correct but has no steps then am sorry. I really want to know how to solve it by myself.

x = 50

51

Step-by-step explanation:

Question 7

This is an isosceles triangle, you can identify this, by its little tick marks on two sides of the triangle. So that means there are two 35 angles. by the rule of triangles, all angles added all together must be 180°

35 + 35 + 2x + 10 = 180

Combine like terms

70 + 10 + 2x = 180

80 + 2x = 180

2x = 180 - 80

2x = 100

2x/2 = 100/2

x = 50

Question 8

First, we need to find x to find angle Y. This is a right triangle as we can see from the square at the corner of the triangle. So, that means, that Angle Z is 90°. We know that all angles of a triangle will add up to 180 no matter what.

3x + 2x + 5 + 90 = 180

Comebine like terms

3x + 2x = 5x

90 + 5 = 95

5x + 95 = 180

5x = 180 - 95

5x = 85

5x/5 = 85/5

x = 17

Angle Y = 3x

3x

3(17)

51°

It says "Enter the value only without the degree symbol" so, 51
