#4 a reflection across the x-axis is the only correct answer , the other ones aren’t correct .
Answer:
B 10/26
Step-by-step explanation:
Cosine is the adjacent side over the hypotenuse.
<h2><u>We can solve it using trigonometric values.</u></h2>
<h3>So , <u> </u><u>sin</u><u> </u><u>θ</u><u> </u> = ( Perpendicular / Hypotenuese )</h3>
<h2><u>Given</u><u> </u></h2>
Perpendicular = x
Hypotenuese = 30


<h2>∴ x ( Perpendicular)= 15√2 <u>Ans</u><u>.</u></h2>
Answer:
He ate 40% of it
Step-by-step explanation:
20/50 is 2/5, which is basically 4/10 therefore equaling 40%
2x^3(x+1)-x(x+1)
(2x^3-x)(x+1)
x(2x^2-1)(x+1)
