A rectangular garden is 17 feet wide. Its length is 3 feet more than twice the width. What is the area of the garden?
sleet_krkn [62]

Answer:

a = 629

Step-by-step explanation:

a = w * L

w = 17

L = 2w + 3

a = (17) * (2w + 3)

a = (17) * (2(17) + 3)

a = 17 * (34 + 3)

a = 17 * (37)

a = 629

24) sin x = 1/3<br> Find cos x.
liq [111]

Answer:

\frac{2\sqrt{2} }{3}

Step-by-step explanation:

The sine of an angle is defined as the ratio between the opposite side and the hypotenuse of a given right-angled triangle;

sin x = ( opposite / hypotenuse)

The opposite side to the angle x is thus 1 unit while the hypotenuse is 3 units. We need to determine the adjacent side to the angle x. We use the Pythagoras theorem since we are dealing with right-angled triangle;

The adjacent side would be;

\sqrt{9-1}=\sqrt{8}=2\sqrt{2}

The cosine of an angle is given as;

cos x = (adjacent side / hypotenuse)

Therefore, the cos x would be;

\frac{2\sqrt{2} }{3}
