Answer:-1/4
Step-by-step explanation:
Take the negative of the reciprocal for perpendicular lines. In the case of no slope (y=number) replace y with x
Y would equal 6.16.
We can use trigonometry and label AC as the hypotenuse and BC as the adjacent side.
This means we have to use the cosine ratio, cos = Adjacent/hypotenuse, and so to find the adjacent we must do cos(44.25) × 8.6, which is 6.16.
I hope this helps!
Answer:
The area is 64squared units
Step-by-step explanation:
Given
Required
The area of the polygon
First, we plot the given coordinates on a plane (See attachment)
From the attachment, we can see that the 4 coordinates make up a square.
Where
So, the area is:
Substitute for
<em>Hence, the area is 64 squared units</em>

Answer:
15 square cm
Step-by-step explanation:
Area of triangle A = 1/2 × b× h
b = 0.5cm and h = 3cm
: A = 1/2 × 0.5 × 3
So for 20 triangle tiles
Total area = 1/2 × 0.5 × 3 × 20
= 15 square cm
