1. emilysoto123

2. Sunshine447

the bottom of the triangle is how many units long?

3. emilysoto123

isn't it 16

4. Sunshine447

yes

5. Sunshine447

it wants you to find the perimeter so you have to first find the hypotenuse

6. Sunshine447

the triangle is made up of two smaller triangles so you have to find the hypotenuse of one of them

7. Sunshine447

since the bottom of both triangles combined is 16, what is the length of only one of those smaller triangles? HINT: its half of the bottom value

8. emilysoto123

8

9. Sunshine447

right. Are you familiar with the pythagorean theorem?

10. emilysoto123

yup a2+b2=c2

11. Sunshine447

okay, so, you have a and b now find c. A=8 and b=15. find C. dont forget to square them

12. Sunshine447

do you know how?

13. emilysoto123

yea

14. Sunshine447

okay, so what is the length of the hypotenuse or one of the smaller triangles?

15. Sunshine447

yup so now you have the value of the bottom of the triangle and the value of both sides. To find the perimeter you have to add the values of all the sides. So whats the perimeter of the triangle?

16. Sunshine447

the sides lengths are 16 17 and 17. whats the perimeter?

17. emilysoto123

50?

18. Sunshine447

yup! good job!
