Find the measure of the marked angles

Answer:
The angle is [tex]45^{o}[/tex]
Step-by-step explanation:
By vertical angles theorem they are equal to each other so it just becomes an algebra problem.
3x+30=8x+5
30=5x+5
25=5x
x=5
Substitute to find the angle
3(5)+30=45
The angle is [tex]45^{o}[/tex]
Step-by-step explanation:
Solution:
(3x+30)°=(8x+5)°{being vertically opposite angles}
or,3x+30°=8x+5°
or,3x-8x=5°-30°
or,-5x= -25°
or,5x=25°{minus minus cut }
or,x=25÷5
or,x=5°
Therefore the value of x is 5°.
