Answer:
√7
Step-by-step explanation:
Let :
AC = x
BD = y ; AD = 3 - y
Since, AD = BC
Then BC = 3 - y
Taking △BDC a d applying Pythagoras
Hypotenus² = opposite² + adjacent²
BC² = CD² + BD²
(3 - y)² = (√3)² + y²
9 - 6y + y² = 3 + y²
-6y + y² - y² = 3 - 9
-6y = - 6
y = 1
AD = 3 - y ; AD = 3 - 1 = 2
Taking △ADC
AC² = CD² + AD²
AC² = (√3)² + 2²
AC² = 3 + 4
AC² = 7
AC = √7
It should be the answer- 3-2y

Answer:
A
Step-by-step explanation:
A percent is a portion of 100. If $15 is 100% of the price, and we pay $9.75 then we saved 15-9.75=5.25. We can then divide our savings bu the total to find the percent. 5.25/15=0.35. We convert the decimal by multiplying by 100.
0.35(100)=35%
