The angle is called an hypotenuse and to find it just use the Pythagorean Theorem which states a squared+b squared= c squared, does this answer your question or do you need more help?
any multiple of 12
Since 2, 3 and 4 divide exactly into the number of rocks
We are looking for the common multiples of 2, 3 and 4
2 × 3 × 4 = 24 is possible but dividing by 2 gives 12 the lowest common multiple
Any multiple of 12 gives a possible number of rocks.
Answer: 3.36
Step-by-step explanation: 75minutes / 28= 2.678571428571429
9/2.678571428571429=3.36 times
This can be factored into (x+9)(x+5)/(x+9)(x+1)
once simplified, it's (x+5)/(x+1)
The denominator cannot be negative, so x≠-1
Therefore, the answer is C.
