Answer: Fourth option is correct.

Step-by-step explanation:

Since we have given that

1) we have

$4x^2=35\\\\x^2=\dfrac{35}{4}\\\\x^2=8.75\\\\x=\sqrt{8.75}\\\\x=2.95$

2) we have

$x^3=64\\\\x=\sqrt[3]{64}\\\\ x=4$

3) We have

$x^3=125\\\\x=\sqrt[3]{125}\\\\ x=5$

4) We have

$x^2=38\\\\x=\sqrt{38}\\\\x=6.16$

So, we can say that x=6.16 is the greatest value of x.

Hence, Fourth option is correct.

Hey mate!
You stuck?

^3 The cube root of 125=5
^2 The square root of 35=5.91
^3 The cube root of 64=4
^2 The square root of 38=6.16

Therefore your answer would be x2= 38, because 6.16 is greater than the other sums.

Hope this helps! :) (Don't forget Brainliest) :)

Answer:

$x \approx 55.8$

Step-by-step explanation:

In order to solve this problem, one must use the trigonometric ratios. These ratios are the following,

$sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)= \frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}$

Remember, each side is named relative to the angle, thus sides will attain different names depending on the angle which one sues to calculate with.

In this case, one is given the measure of the angle, and the measure of the side opposite to the angle. One is asked to find the measure of the side adjacent to the angle. Use the trigonometric ratio ( $tan$ ) to solve for the unknown. Substitute in the given values,
