Answer: G. 12.5, 7.5, 10
Step-by-step explanation:
To determine the lengths of metal that could be used to form the tight angle triangle, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
The hypotenuse is the longest side while the opposite and adjacent sides are the shorter side. Therefore,
F.
8² = 4² + 4²
64 = 16 + 16 = 32
A right angle triangle cannot be formed because they are not equal.
G.
12.5² = 7.5² + 10²
156.25 = 56.25 + 100 = 156.25
A right angle triangle can be formed because they are equal.
H.
23² = 11² + 9²
529 = 121 + 81 = 202
A right angle triangle cannot be formed because they are not equal.
J.
96² = 12.5² + 6²
9216 = 156.25 + 36 = 192.25
A right angle triangle cannot be formed because they are not equal.
1/8 bowl.
1/2 = 4/8
1/4 = 2/8
1/8 = 1/8
4/8+2/8+1/8 = 7/8
1 - 7/8 = 1/8
The answer is -4k^2 - 21k - 20! so sorry if I’m wrong but it’s the answer I got :>
The answer is 7.20 because $18 divided by 2.5% is 7.20
The answers are
1. 18
2. 1 1/15
