Answer:
28pi*66/360
Step-by-step explanation
Used the equation Central angle/360*2pi r
15 - 4 1/3 = 10 2/3
10 2/3 * 3/5 = 6 4/10
10 2/3 - 6 4/10 = 4 4/15
56 is ten percent of the original price.
So 100 percent of the original price would be $560
Answer:
x = 15
Step-by-step explanation:
the opposite angle of a cyclic quadrilateral sum to 180° , then
6x + 20 + 3x + 25 = 180
9x + 45 = 180 ( subtract 45 from both sides )
9x = 135 ( divide both sides by 9 )
x = 15
