To be a right triangle, the hypotenuse^2 must equal side1^2 + side2^2
Only set 2 meets these conditions
8, sq root (29), sq root (35) then squaring these:
64, 29, 35
64 = 29 + 35
Because there are 4 inside angles the sum of the four angles must equal 360 degrees.
Add the angles to equal 360:
4x + 3x + 2x + 3x = 360
Simplify:
12x = 360
Solve for x by dividing both sides by 12:
x = 360 /12
x = 30
Now you have x, solve for each angle:
ABC = 4x = 4 x 30 = 120 degrees.
BCD = 3x = 3 x 30 = 90 degrees.
CDA = 2x = 2x 30 = 60 degrees.
DAB = 3x = 3 x 30 = 90 degrees.
C. It's important to know that a four sides figure needs the inside angles when added together need to equal 360 degrees.
The answer would be 630.75
Made 35%
Missed 65%
I hope this helps :)
C because both equations make -8
