I need to know number 5 just what it says thank you

C

Step-by-step explanation:

Okay! Time to use the Pythagoras theorem.

a^2 + b^2 = c^2

4^2 + 7^2 = x^2

16 + 49 = c^2

65 = c^2

Let's take the square root of both sides to get

c ~ 8.06

C

:)

8.06

Step-by-step explanation:

We know this is a right triangle because of the little rectangle in the corner. Therefore, we can use the Pythagorean Theorem

a^2+b^2=c^2

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

We know that 7 and 4 are the legs, because they form the right angle. c is the hypotenuse, since it is opposite the right angle.

7^2+4^2=c^2

49+16=c^2

65=c^2

Take the square root of both sides

8.06225775=c

To the nearest hundreth:

8.06=c

16
