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!

Answer:

in the explanation

Step-by-step explanation:

According to the triangle midsegment theorem (if these points are midpoints),

2x + 3 is two times longer than 7, meaning it's 14.

2x+3=14

2x=11

x = 11/2

If there is an option for not enough info given, that should be right as it doesn't actually say that they are midpoints
