It's a complementary angle, so just solve for x and subtract the CBD from 90,
First, we have to solve for x.
2x + 14 + x + 7 = 90
Combine like terms
3x + 21 = 90
Balance, subtract 21 from each side.
3x = 69
Divide 3 from each side
x = 23.
So know that we know x is 23, we can go about it 2 ways, subtracting the other angle with 90 or just substituting the variable, I'd just substitute the variable for it so just do 23 + 7. That equals 30, angle ABC = 30.
Answer:
2 Groups
Step-by-step explanation:
if there is 14 kids and you can only drive 7 at a time. You are going to have to make 2 trips because 7 + 7 = 14
3(x-7x)-y
3(-6x)-y
-18x-y
