Answer: a = 150
b = 30
Remember: supplementary angles always add up to 180 degrees. Therefore, using this information, you can easily form your equation.
Form your equation. Since a is five times b, a = 5b.
5b + b = 180 Combine like terms
6b = 180 Divide by 6 to both sides
b = 30 Answer!
Substitute (30) for b in a = 5b to find a.
a = 5(30) Simplify
a = 150 Answer!
Answer:
11-60-61
Step-by-step explanation:
For right triangle, leg^2+Another leg^2=hypotenuse^2
11^2+60^2=61^2
Answer:
21
Step-by-step explanation:
![\frac{v}{7} = 3](https://tex.z-dn.net/?f=%5Cfrac%7Bv%7D%7B7%7D%20%3D%203)
multiple both sides by 7
v = 21
Check:
21/7 = 3
3 = 3
Fraction = designated group / total
So, 11/27
