Question

Solve for X. pls help asap

Answer 1

Answer:

6.7

Step-by-step explanation:

Hypotenuse (h) = 9

base (b) = X

Perpendicular (p) = 6

Now,

Using Pythagoras theorem:

${h}^{2} = {p}^{2} + {b}^{2}$

${b}^{2} = {h}^{2} - {p}^{2}$

${b}^{2} = {(9)}^{2} - {(6)}^{2}$

${b}^{2} = 81 - 36$

${b}^{2} = 45$

$b = \sqrt{45}$

$b = 6.7$

Hope this helps...

Good luck on your assignment..

Answer 2

Answer:

x=3

Step-by-step explanation:

Use the Pythagorean Theorem to write an equation.

x^2+y^2=z^2

Substitute values from the problem.

x^2 + 6^2 = 9^2

Solve for what you know.

x^2 + 36 = 81

Square root it.

x+6=9

Subtract 6 from both sides.

x=3

In the future, if you see a right triangle with an unknown side, and the other two sides are either 3, 6, or 9, you know that the other one is the missing value out of 3/6/9. This is called a 3/6/9 triangle.
