Answer: Obtuse triangle.
Step-by-step explanation:
1. By definition, you have:
- If the square of the length of the longest side is greater than the sum of the squares of the lengths of the other two sides, then the triangle is classified as "obtuse".
- If the square of the length of the longest side is less than the sum of the squares of the lengths of the other two sides, then the triangle is classified as "acute".
- If the square of the length of the longest side and the lenght of the other two sides are equal, then it is a right triangle.
2. Based on this information, you have:


3. The longest side is greater than the other two sides. therefore, it is an obtuse triangle.
Answer:
The distance in one sweep is 100 cm approximately
Step-by-step explanation:
Here, we want to calculate the distance the wiper covers in one sweep
Mathematically;
we have a structure like an arc of a circle. It is the length of this arc we want to calculate.
The formula for the length of an arc is;
theta/360 * 2 * pi * r
r is the radius which in this case is 50 cm
We have ;
115/360 * 2 * 3.1412 * 50 = 100 cm approximately
48 + 23 = 71
The bus started out with 71 students.
F(1)=-10
f(x), so x=1
f(x)=-10, y=f(x), and y=-10
(x,y)=(1,-10)
