The answer would be c
Hope this helps!
Answer:
d. c = 100; (x – 10)²
Step-by-step explanation:
Note that (x+a)²=x²+2ax+a².
In our case, 2a=-20, so 'a' must be -10.
Since c=a², and a=-10, c=(-10²)=100.
Since a=-10, the perfect square is (x – 10)²
If you're looking for "x"
x/3 = 3
x = 3*3
x= 9
The answer is 3/5 because u need to find the missing side in order to find sin
