19/25 * 100 = 1900/25 = 76 ....numbers greater then 15
7/50 * 100 = 700/50 = 14....numbers less then 15
100 - (76 + 14) = 100 - 90 = 10 <== numbers equal to 15
The answer would be 35 students because if you divide both numbers by 35 you get even numbers. You cannot have more students because then it wouldn't be divided evenly.
Both of the other angles are 40° because a triangle has a total angle of 180° and an isosceles triangle means that at least two of the sides have to be the same length (two angles must be the same)
180 - 100= 80
80 ÷ 2 = 40
Answer:
8.94
Step-by-step explanation:
5 - (-3) = 8
3 - (-1) = 4
a²+b² =c²
4² + 8² = c²
c = 8.94
