Answer:
Step-by-step explanation:
So, according to the law of Sines, we have

In our case, we have S and R, so...

And we want to isolate R...

the angle of R is then 75.90 degrees.
The inverse of the function is h(x)=4x+48
According to the definition, is a parabola is in the standard form of (x-h)^2<span>=4p(y-k), then the directrix is y=k-p. In this case, the parabola function is x^2=8y, so h=0, p=8/4=2, k=0. Plug the values of h, p, k, into y=k-p, the directrix is y=-2.</span>
Based on the calculations, the value of x in this rhombus is equal to: B. 55.
<h3>How to determine the value of x?</h3>
Since the opposite angles in a rhombus are always congruent, the sum of each angle in any rhombus must be equal to 360 degrees.
From the image of the rhombus, we can deduce the following parameters:
Adjacent angles = 2x + 20 and 50 degrees.
Opposite angles = 2x + 20 and 50 degrees.
Adding the angles, we have:
2x + 20 + 2x + 20 + 50 + 50 = 360
4x + 140 = 360
4x = 360 - 140
4x = 220
x = 220/4
x = 55°
