Answer:
[tex]\huge\boxed{m \angle 4 = 105 \textdegree}[/tex]
[tex]\huge\boxed{m \angle 5 = 75 \textdegree}[/tex]
[tex]\huge\boxed{m \angle 6 = 105 \textdegree}[/tex]
Step-by-step explanation:
We can use basic angle relationships to find the measures of m∠4, m∠5, and m∠6.
We know that angles m∠3 and m∠2 are supplementary. This means their angle lengths add up to 180°. Since we know the expression for both, we can add them and solve for x.
- [tex](x) + (x+30)=180[/tex]
- [tex]2x+30=180[/tex]
- [tex]2x=150[/tex]
- [tex]x = 75[/tex]
So x = 75°, aka m∠3 is 75°. This means m∠2 is going to be [tex]75+30=105[/tex]°.
m∠4 is an opposite angle to m∠2. This means their angle lengths are the same. Therefore, m∠4 is 105°.
We also know that m∠3 and m∠5 are alternate interior angles, meaning their angle lengths are the same. Since m∠3 is 75°, m∠5 is also 75°.
We also know that m∠6 is a corresponding angle to m∠2. This means their angle lengths are the same. Since m∠2 is 105°, m∠6 is also 105°.
Hope this helped!
