Answer:
90 + x
Step-by-step explanation:
supplementary angles are angles that add up to 180.
90 + 90 = 180
-x + x = 0
90-x + 90 + x = 180.
so, your answer would be 90 + x
Check! lets say X = 6
90-6 + 90 + 6 = 180.
Good luck with your schoolwork/homework!

Answer:
The answer is 91
Step-by-step explanation:
We have the following equality:
Then a must satisfy that 
. So,
or 
.
1) If a=7, then, it follows for the first equality that 56=14b. Then b=4. Finally, substituting b=4 in the first equality we obtain that -64=16-c. So, c= 80. We conclude that
.
As the problem states, we only consider values of a greater than zero. Then 91 is the only solution for 
.
The sale price of the jeans including tax is going to add up to be $34.56.
Answer:
BC= 9cm
Step-by-step explanation:
- You'll need to use the Pythagorean theorem:
a^2 + b^2 = c^2
The slanted side of the triangle is always going to be 'c' because it is the longest side of the triangle.
- Now simplify: 144 + b^2 = 225
I got these numbers because 12^2= 144 and 15^2= 225
- Now find the square root of 81. The answer is 9.
