Answer:
29/4 or 7.25
Step-by-step explanation:
Complimentary angles are two angles that add up to 90
Supplementary angles are two angles that add up to 180
Angle ABC = x
Angle CBD = 7y + 4
Angle DBE = 8y + x
If we can find the measure of angle CBD, then we can find x.
We know that CBD + DBE = 180 because they are supplementary. Therefore...
(7y + 4) + (8y + x) = 180
AND
(7y + 4) + (x) = 90
Now we can use algebra to solve for x and y...
Blah blah blah...
x = 29/4
y = 45/4
Try 1(18) / 2
Just multiply 1 by 18 and divide 18 by 2.
Then we have 9!
The last answer is correct.
Answer:
7.2 + x = 10
Step-by-step explanation:
I did 7.2 + x = 10 Because there was suspose to be a number in between
that we do not know so you have to put 7.2 + x = 10
Then... For the next question (The same question but asking the number in between) The second Question you do 7.2 - 10 and you get 2.8
