Question

How large is an angle whose supplement is three times its complement?

Answer 1

its x=45 or 45 degrees

Explanation:

So to write this down in an equation it would be `y=3z`
and `y=180 - x` and `z=90-x`

x is the unknown angle in question

and y is its suppliment while z is its compliment

soooooooo write it `y=3z` and ya get

now lets simplify this down a tad

`180-x=3(90-x)`
`180-x=270-3x`
`-x+3x=270-180`

`2x=90`
`x=45`
