Solve for x in the diagram below.

x= 20

Step-by-step explanation:

The three angles add to 90 degrees

x+2x+x+10 = 90

Combine like terms

4x+10 = 90

Subtract 10 from each side

4x +10-10 = 90-10

4x = 80

Divide by 4

4x/4 = 80/4

x = 20

x = 20

Step-by-step explanation:

The three angles are complementary to each other.

That means they add up to 90 degrees.

x + 2x + (x + 10) = 90

Combine like terms.

4x + 10 = 90

Subtract 10 on both sides.

4x = 80

Divide both sides by 4.

x = 20

x = 7 and y =10

Step-by-step explanation:

Equilateral triangles mean all the angles are the same and all 3 triangles angles = 180 so its 180/3 = 60

Given this what times 6 gives you 60  so y = 10

Now line B A is the same length as A F so plug in 1 as x for both equations and see if they come out equally - They dont but when you plug in 7 as x they come out equal as 23 so X = 7
