To classify the angle of a triangle (acute, obtuse, or right), you can use slope formula to see if the slopes are perpendicular. If so, it is a right triangle. The distance formula can be applied to figure out whether the triangle is isosceles, equilateral, or scalene. if the triangle is isosceles, then two of the sides will be the same length and one side will be of a different length. If the triangle is equilateral, then all sides will be of the same length. If the triangle is scalene, then all side will be of different lengths.

How to Find the Mean
Add up all data values to get the sum
Count the number of values in your data set
Divide the sum by the count
The mean is the same as the average value in a data set.
Answer:
? = 35
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan ? = opp /adj
tan ? = 33/48
Take the inverse tan of each side
tan ^ -1 ( tan ? ) = tan ^ -1 ( 33/48)
? =34.50852299
? = 35
<em>54 people have at least one sibling.</em>
steps;
1) figure out what it would be in if a decimal ex; 0.75 (75%) is in the hundredths place.
2) divide 75 by 100.
3) times 0.75 by 72.
