The hypotenuse of a right triangle is 26 mm. One leg of the right triangle is 10 mm. What is the length of the other leg? (4 poi
PIT_PIT [208]

Answer:

24 mm

Step-by-step explanation:

Since it is a right triangle, we can use Pythagorean theorem

a^2+b^2=c^2

where a and b are the legs, and c is the hypotenuse.

We know one of the legs is 10, and the hypotenuse is 26, so we can substitute 10 in for a, and 26 in for c.

10^2+b^2=26^2

Solve the exponents

100+b^2=676

Now, solve for b. To do this, get b by itself.

First, subtract 100 from both sides

100-100+b^2=676-100

b^2=576

Take the square root of both sides

\sqrt{b^2}=\sqrt{576}

b=24

So, the other leg is 24 mm

Average salary of all female workers = $37,596

Average salary of all male workers = $45,500
