Step-by-step explanation:
Answer:
it can be. It just depends on what you are interested in. If you are interested in a scientific field then it is an amazing way to use your time. But if you are bot interested in science, it is a waste personally.
Answer:
x=21
Step-by-step explanation:
Notice the right angle. Perpendicular to it on the right, we have two complementary angles, 25, and 3x+2 (you can ignore the parentheses basically). Because they are complementary angles, they will add up to 90, so we can make an equation to solve for x:
25+3x+2=90
3x+2=65
3x=63
x=21
So x=21 is the correct answer. Let me know if you have any questions about my explanation.
Answer:
the desired range is 2 < t < 12.
Step-by-step explanation:
If the third side is 12 (the sum of 5 and 7), we don't really have a triangle, since the 5-unit and 7-unit sides add up to 12 and lie on the third side (of length 12).
Since triangle ABC is acute, all its angles are between 0 and 90 degrees. So the third side can be 12 but not greater. The smallest possible length of the third side is 2, since 5 + 2 = 7.
Thus, the desired range is 2 < t < 12.
