Question

In ARST, the measure of T=90°, the measure of R=9°, and RS = 46 feet. Find the
length of ST to the nearest tenth of a foot.

Answer 1

Answer:

x = 7.2

Step-by-step explanation:

Hey There!

We can find the length of x by using law of sines

law of sines states that a side length divided by sin ( its opposite angle) is equal to another side length divided by sin (its opposite angles) so we setup an equation

$\frac{46}{sin90} =\frac{x}{sin9}$

now we can solve for x

step 1 multiply each side by sin 9

now we have

$x=\frac{46sin9}{sin90}\\x=7.195985392$

So x = 7.195985392

it says to round to the nearest tenth of a foot so x = 7.2
