Sinα=(opposite side)/hypotenuse
cosα=(adjacent side)/hypotenuse
tanα=(opposite side)/(adjacent side)
In a right triangle the longest side is the hypotenuse.
If one angle opposite a side is α, the angle opposite the other side is 90-α (because the sum of all angles must be 180° for any triangle)
I hope that helps as your question is not really clear, if you have any more specific questions, I'd be happy to help out. :)
Answer:
angles are 48°, 48°, 84°
Step-by-step explanation:
ratio of angles = 4 : 4 : 7 = 4x : 4x : 7x ( x is a multiplier )
the sum of the 3 angles = 180 , then
4x + 4x + 7x = 180 , that is
15x = 180 ( divide both sides by 15 )
x = 12
the student made the error of assuming x = 12 was the size of the 2 equal angles.
the correct angles are
4x = 4 × 12 = 48°
4x = 4 × 12 = 48°
7x = 7 × 12 = 84°
12 since 12 is not negative. All absolute values r positive
Answer:
assuming only positive integers, the answer is 1
Step-by-step explanation:
the smallest number that you can get by adding is:
- start with 0
- then add 1 = 1
- add another 1 = 2
- add another 1 = 3
- add another 1 = 4
- add another 1 = 5
but you can also multiply, and anything multiplied by 0 is 0:
- start with 0
- multiply by 2 = 0
- multiply by 2 = 0
- multiply by 2 = 0
- multiply by 2 = 0
- multiply by 2 = 0
The question does not say that we need to do any specific calculation, it only gives us 2 options and we can choose them as many times as we want.
