We assume the base is 12 in × 20 in, so its diagonal has length
... √(12² +20²) = √(144 +400) = √544 = 4√34 . . . inches
Then the tangent of the angle of interest is the ratio of the box height to the base diagonal:
... tan(α) = (7 in)/(4√34 in) ≈ 0.300123
The angle will be the arctangent of this value,
... α = arctan(7/√544) ≈ 0.291569 radians
If AB=AC then It is an isocoles triangle. Because of this, Angle ABC=ACB, meaning they are both 60°. This means that Angle BAC is also 60°. Becasue of circle theorms, the angle BOC=2BAC so angle BOC=120°
You have to be able to take the words written down and put them into mathematical symbols. The word "is" means =, the word "of" means to multiply, "what number" is x, your unknown. So translating that from words to an equation looks like this: 19 = .06x. Divide both sides by .06 to get x = 316 2/3
Hey there! I think Nicole would be 28.
You can put 400/100 to get the fraction 4/1 or 4, it is not a mixed number though. So the final answer is 4
