Sagot :
Answer:
<EFG is 108
Step-by-step explanation:
3x-18 = 2x+12
x = 30
2(30) + 12 =
60 + 12 = 72
180 - 72 = 108
Answer:
108
Step-by-step explanation:
2x+12 and 3x-18 are vertical angles which mean they are congruent. We can write the equation 2x+12=2x-18 from this. When we solve for x, the answer is x=30. Now we can plug 30 into the equation 2x+12 to get 72. Notice that angle 2x+12 added to angle EFG is 180 degrees because they are supplementary. We subtract 72 from 180 to get the resulting answer of 108.
