Answer:
A. 34°
Step-by-step explanation:
The measure of the external angle at X is half the difference of the subtended arcs:
(93° -25°)/2 = 68°/2 = 34°
Answer:
20,34
Step-by-step explanation:
Let the two numbers bw a,b
Their sum is 54
a+b=54⋯(1)
Their difference is 14
a−b=14⋯(2)
(1)+(2)
2a=68
a=34⟹34+b=54
b=54−34=20
Answer:
$18.30
Step-by-step explanation:
First, you can figure out the cost per golf ball by dividing the price by the number of golf balls. If 6 balls = 7.32, then 1 ball = 7.32/6, or 1.22. Now you can multiply this by the number of balls in the box to find out the price: 1.22 * 15 = 18.30.
Another way to solve this is to set up a ratio of balls / price:
(<em>x </em>is the unknown price)
Now, cross-multiplying, you find that 6x = 7.32 * 15, or 6x = 109.8. Dividing both sides by 6, you get x=18.30.
