Answer: x = 10.5
======================================
Work Shown:
BC*BD = AB*AB
2*(2+x) = 5*5
4+2x = 25
2x = 25-4
2x = 21
x = 21/2
x = 10.5
12 I think because you take 22 divided by 1 and 5/6.
Answer:
Level 2:
45 x 45 = 2025
28 x 28 = 784
2025 + 784 = 2809
(sqrt)2809 = 53
<u>53 units</u>
Level 3:
(Start by graphing the coordinates)
Your shape should have one leg of 14 units, and one leg of 8 units.
14 x 14 = 196
8 x 8 = 64
196 + 64 = 260
(sqrt)260 = 16.1245155
(rounded to nearest tenth)
<u>16.1 units</u>
<u></u>
I`m not sure about the other two though, sorry :/
