Question

The answer is 7 but does anyone know how to show the work ?

Answer 1

uhh sorry man no can do

Explanation:

Answer 2

x = 7

Explanation:

An inscribed angle represents half of its intercepting arc. So what I did was add
`19x + 13` and
`90` which comes to
`19x + 103`

Angle Q would be half of
`19x + 103`.

`Q = (19x +103)/(2)`

The opposite of Q is
`7x + 13`.

I will call this angle "y" just to explain.

y + Q = 180

This means we just have to plug everything in.

`7x + 13 +(19x + 103)/(2) = 180`

Solve for x.

`7x +(19x + 103)/(2) = 167`

`2(7x +(19x + 103)/(2)) = (167)2`

`14x +19x +103 = 334`

`33x = 231`

`x = 7`

I haven't done geometry is forever so I really hope this makes sense and it helped you! :)
