Answer:
No
Step-by-step explanation:
Feet is a measurement of length.
Surface area requires a measurement of area.
You can use square feet to measure surface area.
If you multiply two values in the foot unit together, you have square feet.
You can multiply the number and the answer is d
None of the x-values are repeating so it's C (I did this last year in algebra 2)
Let n = one of the angles
Let 2n -30 = the other
n+ 2n -30 =90⁰ (because they are complementary)
Combine like terms -- 3n -30 = 90
Add 30 to both sides of the equation
3n=120°
Divide both sides by 3 and n=40° 2n -30 = 80 -30 = 50°
So one angle is 40° and the other is 50° and those angles are complementary.
Answer:
x/9
Step-by-step explanation:
x divided by 9
=> x ÷ 9
<em>Take that and turn it into a fraction</em>
=> x/9
hope this helps and is right. p.s. i really need brainliest :)
