Answer:
Part a) The measure of the missing angle is 
Part b) The triangle of the figure is a right triangle
Part c) The triangle of the figure is a scalene triangle
Step-by-step explanation:
we know that
The sum of the interior angles of a triangle is equal to 
so
Let
x------> the missing angle
we know that
solve for x
The triangle of the figure is a right triangle --------> by its angles
Because the triangle has an angle measure of
The triangle of the figure is a scalene triangle --------> by its sides
Because the three angles and the three sides measures are different
Answer:
Option C. X=A/4
Step-by-step explanation:
we know that
The area of the rectangular post it note is equal to
where
L is the length
W is the width
In this problem we have
substitute
solve for x
That means ----> isolate the variable x
Divide by 4 both sides
Answer: Total distance travelled is 510 km
Step-by-step explanation:
it is given that an automobile travels for
2 hours at 80km/h
3 hours at 110km/h
30 min at 40km/h
to find distance=x(let)
since
distance = speed * time
so
x= 80*2 +110*3 +40*(1/2) [since 1 hour =60 min so 30 min =1/2 hour]
x=160+330+20
x=510
hence total distance travelled is 510 km
