Answer 1

the sum of inner angles of a pentagon is equal to

`n - 2 * 180 = (5 - 2) * 180 \\ 3 * 180 = 540`

so:

`x + 10 + x + 20 + 2x + 10 \\ + x + 10 + 2x = 540 \\ 7x + 50 = 540 \\ 7x = 490 \\ x = 70`

and the largest one is 150

`2x + 10 = 2(70) + 10 = 150`

the answer is 1/16

`4 {}^( - 2) = \frac{1}{4 {}^(2) } = (1)/(16)`

the parallel line can be

y=2x+4

or any line with different y intercept

good luck
