Supplementary means that they add up to 180 degrees. Those 2 angles should add up to 180 degrees. X is the missing angle and 42 degrees is the other angle. If both are added together they equal 180. To find x we can simply subtract 42 from 180 to get the x. 138 is x. The proof is that if 138 and 42 are added together they end up making 180 degrees. Therefore, the answer is 138
Answer:
Step-by-step explanation:
5^2 + 10 ÷ 2
25 + 10 ÷ 2
25 + 5
30
9a)
4x - 2 + 30 = 68
4x + 28 = 68
4x = 40
x = 10
9b)
y = 180 -68
y= 112
Answer:
The answer to your question is below
Step-by-step explanation:
See the picture below
Data
A (-2, 3)
B (4, 5)
I plotted the points C (4, 3) and D (-2, 5)
Distance
dAC = 
= 
= 6
dBD = 
= 
= 6
dAD = 
= 
= 2
dBC = 
dBC = 
dBC = 2
Total distance = dAC + dBD + dAD + dBC
Total distance = 6 + 6 + 2 + 2
= 16
I calculate the length of each side and then I sun them up.
X=7 because if an angle is bisected it is divided into two equal part so both sides must equal twenty five so you replace seven for X and you have 5(7)-10 you do the math five times seven equals thirty five minus ten is twenty five.
