Answer:
A
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
2x = 8 ( divide both sides by 2 )
x = 4
Answer:
39°
Step-by-step explanation:
the answer is 39°...

In slope intercept form it would be
Y = -x -3
Answer:
A. (x-5)(x-5)
Step-by-step explanation:
We need to factor x^2-10x+25 into the form (x+y)(x+y) where 2y=-10 and y^2=25
2y=-10
y=-5
So this becomes (x-5)(x-5)
Hope this helped!
