Do 2x2 first which is 4 and then 5+12 which is 17 . 17/4 is 4.25
Answer:
x = 6
Step-by-step explanation:
Verticle angles are formed when two lines intersect. The angles opposite each other are congruent, those angles are called vertical angles.
Using this knowledge, one can say;
3x + 2= 20
Use inverse oeprations to solve for "x"
3x + 2 = 20
-2 -2
3x = 18
/3 /3
x = 6
For the first one it's 90.5, I know cause I just took the test and it's right. The second one I'm not sure..
