Use the Pythagorean theorem $a^{2} + b^{2} = c^{2}$ to find the missing side length of a right triangle

In this case, after you plug in the given numbers your equation is $12^{2} + y^{2} = 20^{2}$

Then, Just solve that equation for y.

$144 + y^{2} = 400$

$x^{2} = 256$

$\sqrt{} y^{2} = \sqrt{256}$

y = 16

So the answer is B, 16 cm.

I hope this helps, please feel free to ask questions if you're still confused :)

A, B and C are collinear points. B is between A and C. AB=12 BC=18 AC=3x Find X.

SCORPION-xisa [38]

Answer:

$x =10$

Step-by-step explanation:

Given

$AB = 12$

$BC = 18$

$AC = 3x$

Required

Solve for x

Since B is in between both points, then:

$AC = AB + BC$

This gives

$3x = 12 + 18$

$3x = 30$

Divide by 3

$x =10$

What is the area of FGH

Dmitrij [34]

54 $in^{2}$

A right triangle is a shape that looks like half of a square. The height of the triangle is 12, and the base of the triangle is 9. To find the area, use the following formula:

A = $\frac{bh}{2}$

= $\frac{12x9}{2}$

= $\frac{108}{2}$

= 54 $in^{2}$

The speed of light is about 1.9 x 10^5 miles per second. It takes about 500 seconds for light to travel from the Sun to Earth.

lukranit [14]

We are 93,000,000 miles away from the sun. The answer should be 9.3 x 10^7.

What is the value of f(3)

Elden [556K]

if x = 3

3 > -1, and so you use the x² formula.

Plug in 3 for x

x² = (3)²

Simplify

3² = 3 x 3 = 9

9, or (A), is your answer

hope this helps
