Question

1 what it's the measure please

Answer 1

The answer to your question would be 20°.
If the measurements are : 4 and angle 8
the equation would be:

3x=x+402x=40x=40/2x=20
We can conclude that the measure of angle of is 20°

Answer 2

Remember that vertical angles are pairs of opposite angles made by two intersecting lines. Since vertical angles are congruent, we can equate the measures of angle 4 and angle 8 and solve for
`x`:

`3x=x+40`

`2x=40`

`x= (40)/(2)`

`x=20`

We can conclude that the measure of angle of is 20°
