Answer:
Yeah
Step-by-step explanation:
Answer:
254/324 which is about 78.4%
Step-by-step explanation:
found area of entire square to be 18² or 324
found area of 4-quarter circles - which equals one circle with radius of 9
A = 81π which is about 70
subtracted 324 and 70 to get 254
ratio of shaded to unshaded is 254 : 324
The order of the sides of the triangle is bc>ab>ac as per the rule that side opposite to the larger angle is larger
Using Isosceles triangle theorem we can determine that JI = JK
Thus
5x + 4 = 2x+7
3x = 3
x=1
Plug it back into the eqution for JK
2(1) + 7 = JK
9 = JK
