Pls hurry!!!!!!! What value(s) of x will make x^2 = 100 true?

Mathematics

Darya [45]3 years ago
4 0

Answer:

\large\boxed{\fcolorbox{x=10 }{}{}} OR \large\boxed{\fcolorbox{x=-10 }{}{}}

Let's solve the equation step-by-step:

First, you must find the square root:

x = ± \sqrt{100}

We know that 10 × 10 = 100 and -10 x -10 is 100

that means that the square root is either  10 or -10

And we also know that 10^2 -10^2 are both 100

meaning that x = 10^2 OR -10^2

What is the length of EF in the triangle? Show your work. HELP!
Zinaida [17]

The length of EF in the given triangle is 8.80 m.

Step-by-step explanation:

Step 1:

In the given triangle, the opposite side's length is 16.2 m, the adjacent side's length is x m while the triangle's hypotenuse measures 16.2 m units.

The angle given is 90°, this makes the triangle a right-angled triangle.

So first we calculate the angle of E and use that to find x.

Step 2:

As we have the values of the length of the opposite side and the hypotenuse, we can calculate the sine of the angle to determine the value of the angle of E.

sinE = \frac{oppositeside}{hypotenuse}  =\frac{13.6}{16.2} = 0.8395.

E = sin^{-1} (0.8395), E = 57.087.

So the angle E of the triangle DEF is 57.087°.

Step 3:

As we have the values of the angle and the hypotenuse, we can calculate the cos of the angle to determine x.

cos E = \frac{adjacentside}{hypotenuse} = \frac{x}{16.2} .

cos(57.087) = 0.5433, x = 16.2 (0.5433) = 8.8014.

Rounding this off to the nearest hundredth, we get x = 8.80 m.
