Answer:
Triangles A & C are right triangles.
Step-by-step explanation:
Triangles A & C are right triangles because they make a 90 degree angle were a pair of legs intersect. That box in the corner of each triangle indicates that the triangle is 90 degrees, therefore a right triangle.
Answer:
3.14
Step-by-step explanation:
First find the circumference of the circle:
= Circumference.
= 
Find the ratio of the angle in relation to the entire circle:
is what we have. So:
Use the ratio and multiply the circumference to find the length:
= 
Round answer to the hundredth:
Answer:
kilometers per hour.
Step-by-step explanation:
We have been given an 
, which describes the number of kilometers y that a van travels in x minutes. We are asked to to find the constant speed of the van in terms of hours.
We can see that van travel 
kilometers in x hours. To find the constant speed of van, we will substitute 
in our given equation as:
Since van travels 
kilometers in one hour, therefore, constant speed of van is kilometer per hour or 
kilometers per hour.
