THE ANSWER IS DOWN BELOW :)

Answer 2

The value of x is
`15\°`

Explanation:

we know that

If two angles are complementary, then its sum is equal to
`90\°`

In this problem we have that

`m<1+m<2=90\°` ------> equation A

we have

`m<1=x\°`

`m<2=(3x+30)\°`

Substitute the values of m<1 and m<2 in the equation A and solve for x

`x\°+(3x+30)\°=90\°`

`4x=90\°-30\°`

`4x=60\°`

`x=60\°/4=15\°`
