90+ POINTS PLEASE HELP Choose one problem below and use trigonometry to solve for a missing angle x of the right triangle

d1i1m1o1n [39]

Answer:

$x\approx49.3266\textdegree$

Step-by-step explanation:

So we want to find Angle x.

Note that we already know the side length of the side opposite to Angle x.

We also know that the hypotenuse is 56.3.

Therefore, we can use the sine function. Recall that:

$\sin(x)=\frac{\text{opposite}}{\text{hypotenuse}}$

The opposite side is 42.7. The hypotenuse is 56.3. Substitute:

$\sin(x)=\frac{42.7}{56.3}$

Take the inverse sine of both sides.

$\sin^{-1}(\sin(x))=\sin^{-1}(\frac{42.7}{56.3})$

The left side cancels:

$x=\sin^{-1}(\frac{42.7}{56.3})$

Use a calculator. Thus:

$x\approx49.3266\textdegree$

And that's our answer :)

The distance between two cities on a map is 3.25 centimeters. The map used a scale in which 1 centimeter represents 20 kilometer

____ [38]

Answer:

Step-by-step explanation:

Step one:

given

we are told that the distance is 3.25cm on the map

the scale is 1cm to represent 20km

Required

the actual distance

Step two

if 1cm represent 20km

then 3.25cm will represent x km

cross multiply we have

x=2.35*20

x= 65km

Hence, the actual distance between these two cities in kilometers 65km
