Kind of true and kind of false : Sometimes they are, but there is nothing that force two acture triangles to be similar, even if they have the same measurement of the acute angle.
For that you would need to have 3 angles the same.
For example, if the angles were 40-60-80, you have an acute triangle. But if you had a 45-55-80 triangle, that is also acute, but not similar even though it shares an angle of 80 degrees.
It would be 282.7 or 283 for the total surface area. Since the radius is three and the height is 12.
Answer:
2.37 
Step-by-step explanation:
Multiply all dimensions of the rectangular prism
length x width x height = volume
4/3 cm x 4/3 cm x 4/3 cm = 2.37
Answer in Mixed Number: 
Answer in Improper Fraction: 
I think your answer would be D.0562
So the equation to find the discriminant is 
, with a = x^2 coefficient, b = x coefficient, and c = constant. Using that formula, our equation is 
- Firstly, solve the exponent and multiplications:
- Next, do the subtraction, and your discriminant is -23.
Now because the discriminant is <u>less than zero</u>, there are <u>no real solutions.</u>
