Answer:

$\Huge\boxed{x=71.9}$

Step-by-step explanation:

Hello There!

Once again we are going to use trigonometry to solve for x

Here are the Trigonometric Ratios

sin = opposite divided by hypotenuse

cos = adjacent divided by hypotenuse

tan = opposite divided by adjacent

we need to find x and we are given its opposite side length (58) and the adjacent side length (19)

this corresponds with tangent so once again we will be using tangent to solve for x

Looking at tangent we see that its equal to opposite divided by adjacent so we create an equation

$tan(x)=\frac{58}{19}\\\frac{58}{19} =3.052631579$

now we have

$tan(x)=3.052631579$

Once again we need to get rid of the tan

to do so we take the inverse of tan ( tan^-1) and apply it to each side

$arcsin^-^1(tan(x))=x\\arcsin^-^1(3.052631579)=71.86191784$

finally we round to the nearest tenth

we're left with x = 71.9

This problem uses the Richter scale for the strength of an earthquake. The strength, W , of the seismic waves of an earthquake a

olga55 [171]

By using formula given above, M= log(w/w_0), we can find
10^M= w/w_0, it means 10^M.w_0,= w
but M=6.5, so 10^6.5=3162277,66

the seismic waves of the Caracas earthquake were 3162277,66 times more powerful of the standard seismic waves

The diameter of Jupiter is 142.984 Km. The surface area of Saturn is 59.9% the surface area of Jupiter. What is Saturn's diamete

Otrada [13]

Suppose that both planets are spherical. radius of Saturn =142984/2=71,492

Area of Jupiter = 4πr² ==>4π(71,492)² =6.4228 x 10^10

Area of Saturn ==>(6.4228 x 10^10)x(0.599) ==>3,84726 x 10^10

Radius of Saturn = 4πr² =3,84726 x 10^10==> r²=3,0219 x 10^10
and r √(,0219 x 10^10) = 174.000 km & D = 384,000 km
