Hello!

You can use the Pythagorean Theorem

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

c is the hypotenuse which is the side across the right angle
a and b are the other sides

Put in the values you know

a^{2} + 5^{2} = 12^{2}

Square the numbers

a^{2} + 25 = 144

Subtract 25 from both sides

a^{2} = 119

Take the square root of both sides

a = 10.9

The answer is D) 10.9 centimeters

Hope this helps!

I need help on my math
shtirl [24]

Answer:

y = -5/4x - 4

Step-by-step explanation:

The equation they give you is in slope intercept form.  y=mx+b.  The m is the slope (-5/4).  Since they want a parallel line you keep the same slope for point slope form.  Point slope formula is y-y1=m(x-x1). the y1 and x1 are where you plug in the coordinates they give you.

y - 1 = -5/4x (x + 4)

y - 1 = -5/4x - 5

y = -5/4x - 4
