Answer:
160°
Step-by-step explanation:
The formula below gives the measure of an interior angle of a regular polygon of n sides.
[(n - 2)180]/n
[(18 - 2)180]/18
16(10)
160

2400 + 100x = 2200 + 120x
2400 - 2200 = 120x - 100x
200 = 20x
200/20 = x
10 = x <== they would have to sell 10 systems
Answer:
25
Step-by-step explanation:
The Side Splitter Theorem says that if a line intersects two sides of a triangle and is parallel to the third side of the triangle, it divides those two sides proportionally. Therefore:
6/15 = 10/?
6*? = 10*15
? = 10*15/6
? = 25
You cross multiply
a c
- = -
b d
if ad equals bc, then the fractions are equivalent
