To actually form a triangle, the two SMALLEST sides, have to be bigger than the BIGGEST number, when added together.
A.) Can be a triangle
B.)Can be a triangle
C.)Can be a triangle
D.)Can't be a triangle
2+10=12, and 12 is not bigger than 20.
Thus, D, is your answer.
Answer:
BD = 14
Step-by-step explanation:
Using Pythagoras' identity on Δ's ADC and ABC
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, thus
BC² + 12² = 15²
BC² + 144 = 225 ( subtract 144 from both sides )
BC² = 81 ( take the square root of both sides )
BC = = 9
and
DC² + 12² = 13²
DC² + 144 = 169 ( subtract 144 from both sides )
DC² = 25 ( take the square root of both sides )
DC = = 5
Hence
BD = BC + DC = 9 + 5 = 14
divide 2 b 3
2 divided by 3 = 0.625
move decimal point 2 places to the right to turn to a percentage
0.625 = 62.5%
Answer:
3710.67 mm
Step-by-step explanation:
The formula is a^2 h/3
a = 22 h = 23
First, do 22 squared which is 484.
Now do 23 divided by 3 which is 7.666666667
Now multiply 484 and 7.666666667 together to get
3710.666667 or 3710.67 mm
