Question

NEEEEEEEEEEEEEEEEEEEDDDDDDDD HELP

Answer 1

Answer:

Step-by-step explanation:

1.

19² = 17² +x²

19² - 17² = x²

√361-289 =x

√72 = 8.5 ≈ x

Area = base*h/2 = 17*8.5/2 ≈ 72.3

Perimeter = 19+17+8.5= 44.5

and so on...

2.

x²= 5² +13²...

A= 5*13/2 =...

P= 5+13+x=...

3.

20² = 10² +x²...

A=10*x/2=...

P=20+10+x=...

4.

x² = 5² +14²...

A=5*14/2 =...

P= 5+14+x = ...
