Find the value of t, rounded to the nearest tenth
sergij07 [2.7K]

<u>Given</u>:

Given that RST is a right triangle.

The measure of ∠R is 35°.

The length of ST is 12 units.

The length of the hypotenuse is t units.

We need to determine the value of t.

<u>Value of t:</u>

The value of t can be determined using the trigonometric ratio.

Thus, we have;

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

where \theta=R, the side opposite to ∠R is ST and hypotenuse is SR.

Substituting these values, we get;

sin \ R=\frac{ST}{SR}

Substituting ST = 12 and SR = t, we get;

sin \ 35^{\circ}=\frac{12}{t}

Simplifying, we get;

t=\frac{12}{sin \ 35^{\circ}}

t=\frac{12}{0.574}

t=20.9

Thus, the value of t is 20.9 units.

I will give a brainliest to the person who has gets the correct answer with an explanation of how you solved it.

Answer: V = 24,416.64m^{3}

Step-by-step explanation:

Solve for v  by simplifying both sides of the equation, then isolating the variable.

Formula: v = \frac{4}{3} \pi r^{3}

Plugin the variable: v = \frac{3}{4}\pi (18^{3})

Solve:

v = \frac{4}{3} 3.14 (5,832)

v = 4.18666666(5,832)

V = 24,416.64m^{3}
