You would do 157.5/35 to find how much gas she needs
157/35=4.5
She'll need 4.5gallons of gas
The formula to find the measure of an interior angle is

, where

represents the number of sides in the polygon. In this problem,

would represent

.
Let's plug in the value for


Let's simplify that.

Now we know that the <span>measure of an interior angle of a regular three-sided polygon is 60</span>°.
Your answer would be B!Let me know if you have any questions regarding this problem!
Thanks!

Answer:
Im late and I could be wrong but is it 3/100?
Step-by-step explanation:
Answer:
7n-25 < -39
Step-by-step explanation:

↝ Form into
where a > 0 (Optional)
↝ Multiply -1 for both sides.
↝ Then proceed with the Quadratic Formula.
x = [-b ± (√b²-4ac)]/2a ↝ Quadratic Formula

↝ As you can see that inside the square root, the numbers cannot be negative. Therefore, the solutions are imaginary.
↝ Solution with Real Numbers System ↝ There are no real solutions.
↝ Solution with Complex Number System ↝

Therefore, the answer for Complex Number System is (5±√7i)/2
