Jaden is flying a kite with an angle of elevation of 33 degrees. If Jaden lets out 275 feet of string, how high above the ground

pshichka [43]

Answer:

149.8 feet

Step-by-step explanation:

θ = Angle of elevation = 33°

The length of string Jaden lets out = Hypotenuse = 275 feet.

How high above the ground that the kite is flying = Opposite Side.

We are solving this question using the Trigonometric function of Sine

Sin θ = Opposite Side/Hypotenuse

Sin 33 = Opposite/275 feet

Cross Multiply

Sin 33 × 275 feet = Opposite

Opposite side(Height ) = 149.77573463 feet

Approximately to the nearest tenth = 149.8 feet

Molly's town voted on a new speed limit. Out of 38 votes, 19 were in favor of the new speed limit. What percentage of the votes

RUDIKE [14]

Answer:

Percentage of votes in favour of new speed limit=50%

Step-by-step explanation:

There was a voting in Molly's town to set a new limit for the speed attained by a vehicle.

In Molly's town,

Number of votes recorded=38

Number of votes in favour of the new speed limit=19

We have to find the percentage of votes in favour of the new speed limit.

For that,the percentage of votes in favour= $\frac{votes in favour of new speed limit×100}{total votes}$

Percentage of votes in favour= $\frac{19*100}{38}$

Percentage of votes in favour=50%
