Answer:
92in^2
Step-by-step explanation:
Find the length of the bottom right triangle.
Use Pythgoras theorem
You will get 8
(1/2)(6)(2)(2)= 12
12+(10)(8)=92
66!
Surprised I got that.
360 - 42 - 42 - 72 - 72 = 132
132 / 2 = 66
If you look opposite from where the angles are given they are the same angles.
2.5 b = 27.5
b = 27.5 / 2.5
b = 11
If you take away the 0s you can multiply 8 and 3. sooooo
3x8=24
we know that
The formula to calculate the slope between two points is equal to
we have
Step 1
<u>Find the slope GH</u>
substitute in the formula
Step 2
<u>Find the slope HJ</u>
substitute in the formula
Step 3
<u>Find the slope JG</u>
substitute in the formula
Step 4
Verify if triangle GHJ is a right triangle
we know that
if two lines are perpendicular, then the product of their slopes is equal to minus one
so
compare slope GH with slope JG
we have
-----> side GH and side JG are perpendicular
The triangle GHJ is a right triangle
