Answer:
13.6 units (to 3 significant figures)
Step-by-step explanation:
C ( -4,6) and D (-4,-5)
the formula for distance is : √(x2 - x1)² + (y2-y1)²
in this case x1= -4 , x2= -4 and y1 =6 , y2 = -5
so substitute the values and you will get the answers
Answer:
The measure of the reference angle is 
Step-by-step explanation:
The reference angle of an angle is the magnitude of the smallest angle it makes with the x-axis. In this case, we have 
(*Note:

Answer:
20/45 & 21/45
Step-by-step explanation:
Find a common denominator. What you do to the denominator, you do to the numerator. In this case, the smallest denominator is 45.
(4/9)(5/5) = 20/45
(7/15)(3/3) = 21/45
The two fractions you have is:
20/45 for 4/9
21/45 for 7/15

Answer:
132cm ^ 2
Step-by-step explanation:
First solve the top rectangle, 4x7 = 28cm
then solve the bottom rectangle, 8x7 = 56cm
then solve the triangle, we know the entire bottom is 19cm, and 7 is subtracted, thereforth leavin 12, since there is 2 triangles its a base of 6, with a height of 8 making 48cm (and since there is 2 triangles no need to divide by 2)
28+56+48 = 132cm^2
