12 x 13 = 6=156
156 square feet
Since it has 3 congruent sides, it must have 3 congruent angles. This triangle is an equilateral triangle. So this means that you’ll have 6x=180 and x=30
Clarissa jumped 2 3/8 below the qualifying height, while Anika jumped 1 5/6 above.
To solve, note that Clarissa's is - 2 3/8, while Anika's is 1 5/6, and that Anika is more
Subtract
1 5/6 - (-2 3/8)
Change each into improper fraction
1 5/6 = 6/6 + 5/6 = 11/6
2 3/8 = 16/8 + 3/8 = 19/8
11/6 - (-19/8)
Note that two negatives = one positive
11/6 + 19/8
Find common denominators. In this case, use 24
11/6(4/4) = 44/24
19/8(3/3) = 57/24
Combine like terms
44/24 + 57/24 = 101/24
Simplify
101/24 = 4 5/24
4 5/24 inches is how much higher Anika's jump was compared to Clarissa's.
hope this helps
