In ΔTUV, the measure of ∠V=90°, the measure of ∠U=55°, and VT = 82 feet. Find the length of TU to the nearest tenth of a foot.
Degger [83]

<u>Given</u>:

Given that TUV is a right triangle with measure of ∠V=90°

The measure of ∠U = 55°, and the length of VT is 82 feet.

We need to determine the length of TU.

<u>Length of TU:</u>

The length of TU can be determined using the trigonometric ratio.

Thus, we have;

sin \ \theta=\frac{opp}{hyp}

where \theta=55^{\circ}, opp = VT and hyp = TU

Thus, we have;

sin \ 55^{\circ}=\frac{VT}{TU}

Substituting the values, we have;

sin \ 55^{\circ}=\frac{82}{TU}

Simplifying, we have;

TU=\frac{82}{sin \ 55^{\circ}}

TU=\frac{82}{0.819}

TU=100.1

Thus, the length of TU is 100.1 feet.

Lara found the volume of a sphere with a diameter of 10.
Paraphin [41]

Answer:

No, she used the diameter instead of the radius measure.

Step-by-step explanation:

we know that

The volume of the sphere is equal to

V=\frac{4}{3}\pi r^{3}

we have

r=10/2=5\ units ----> the radius is half the diameter

substitute

V=\frac{4}{3}\pi (5)^{3}

V=\frac{500}{3}\pi\ units^{3}
