Question

Please help me ASAP!!!! Find the value of x

Answer 1

Use Pythagorean theory

C^2 = a^+ b^2

In this case you have c and a

B^2= c^2-a^2

B^2 = 12^2-5^2

B^2= 144-25

B^2 = 119

Square root both sides

X= 10.90871

Answer 2

This is a right triangle and to find the length of the missing side you must do pythagorean theorem:

$a^{2} +b^{2} = c^{2}$

a & b are the legs of a right triangle

c is the hypotenuse. This is the side opposite the right angle

In this case each value is:

a = 5

b = x---------------> This is what you are looking for

c = 12

^^^Plug these number into the pythagorean theorem

$5^{2} +x^{2} = 12^{2}$

25 + $x^{2}$ = 144

Isolate x by subtracting 25 to both sides

$(25-25) + x^{2} = 144 - 25$

$x^{2} = 119$

The opposite of squaring a number is taking the square root of a number, so to isolate x take the square root of both sides.

$\sqrt{x^{2} } } =\sqrt{119}$

x = 10.9087121146

Then if the question requests it, you can round  10.9087121146

Hope this helped!
