Answer:
X= 150º
Y= 60º
(I strongly recommend reading the explanation so you can understand it because its way easier than you think!!)
Step-by-step explanation:
2x+90=5x
-2x -2x
90=3x
x=30
2(30)+90= 150º
5(30)=150º
Angle x= 150º
Both angles are congruent because they are vertical angles!!
Now we gotta figure out y so you see that there are two lines crossing. (Both sides will work for this) Both angles are supplementary angles which means they combine to make a 180º angle. So if we already know both sides of x are 150º then we can infer that 150+y=180. All you have to do now is subtract 150 from 180 and you will get y.
180º-150º= 30º
Angle y= 30º
But that is not all do not forget that is says (3y)º which means we gotta multiply y by 3.
Sooo 30 x 3 is 60º
Therefore that angle is 60º
