Answer:
Line A and Line C are parallel
Step-by-step explanation:
<u>Slope Equation: </u> 
<u>Step 1: Find the slope of the first line</u>
Line a passes through (-1, -2) and (1, 0).



<u>Step 2: Find the slope of the second line</u>
Line b passes through (4, 2) and (2, -2).



<u>Step 3: Find the slope of the third line.</u>
Line c passes through (0, 2) and (-1, 1).



Answer: Line A and Line C are parallel
Answer:
357 mi²
Step-by-step explanation:
The shape is made of a triangle and a half-square
we will calculate the area of each one
let A1 be the area of the half-circle:
A1= (10²*π)/2 = 50π mi²
Let A2 be the area of the triangle:
A2= 10*20=200 mi²
let At be the total area:
At =A1+A2= 200+50π =357.07≈ 357 mi²
So I think it would be 55 because the base times the height = 15 and base length = 40
Answer:
41 °
Step-by-step explanation:
