Answer:
The geometrical relationships between the straight lines AB and CD is that they have the same slope
Step-by-step explanation:
Given
Required
The relationship between AB, CD
Since AB is a straight line and O is the origin, then:
Where:
====>
====>
This implies that:
So:
So, we have:
Calculate the slope (m) of
For AB
For CD
By comparison:
This implies that both lines have the same slope
Answer:
Scalene triangle as there are no sides given.
or,
Measure it using a ruler and classify it based on the result.
Step-by-step explanation:
Scalene triangle = No sides are equal.
Isosceles triangle = 2 sides equal.
Equilateral triangle = All sides equal.
Right angled triangle = One angle is 90.
Since, the picture hasn't given any sides, i am gonna say it's a scalene triangle.
If, the triangle is for measure, measure it using a ruler and classify it based on the result.
Distance÷time
440÷8= 55
Therefore he needs to drive at the speed of 55 miles/hour
Answer:
B.
Step-by-step explanation:
Option B is correct - angle ABE is less than 90 degrees, therefore it is acute, and angle DBC is greater than 90 degrees, therefore it is obtuse.
