The diagonals are congruent.
hope this helped.
Answer:
slope =
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (3, 9) and (x₂, y₂ ) = (- 2, 8)
m = = =
Remember, you can do anything to an equation as long as you do it to both sides
we hate fractions so times both sides by 4
4A+8x-7x=8x+24a+8
combine like terms
4A+x=8x+24a+8
minus x both sides
4A=7x+24a+8
minus (24a+8) from both sides
4A-24a-8=7x
divide both sides by 7
These sides will form a triangle because the longest side (302) is less than the sum of the other 2 sides. http://www.1728.org/trianinq.htm
Using Heron's formula, we first have to determine the semi-perimeter of the triangle. (perimeter divided by 2)(240 + 121 + 302) / 2 = 331.50 = semi-perimeter (s)
Now, to use Heron's formula:area = square root (s • (s - a) • (s - b) • (s - c))area = square root (331.5 • (331.5 - a) • (331.5 - b) • (331.5 - c))area = square root (331.5 • (331.5 - 240) • (331.5 - 121) • (331.5 - 302))area = square root (331.5 • (331.5 - 240) • (331.5 - 121) • (331.5 - 302))area = square root (331.5 • (91.50) • (210.5) • (29.5))area = square root ( 188,355,689.44 )area = 13,724.27
