Palelogram area:
Knowing the base and the height, the area of the parallelogram is calculated by its formula:
A1 = b * h
Where
b: base
h: height.
We have then
b = root ((- 4 - (- 10)) ^ 2+ (2-2) ^ 2) = 6
h = root ((- 7 - (- 7)) ^ 2+ (3-2) ^ 2) = 1
A1 = (6) * (1) = 6 units ^ 2
Rectangle area
A2 = L * W
Where
L: long
W: Wide
We have then:
L = root ((1 - (- 2)) ^ 2 + (- 3 - (- 4)) ^ 2) = 3.16227766
W = root ((- 4 - (- 2)) ^ 2+ (2 - (- 4)) ^ 2) = 6.32455532
A2 = (3.16227766) * (6.32455532)
A2 = 20 units ^ 2
The total area is the sum of both ares:
A = A1 + A2
A = 6 + 20
A = 26 units ^ 2
Answer:
the area of this figure
A = 26 units ^ 2
The answer is C. 9. Hope this helps!
Answer:
Step-by-step explanation:
To calculate slopes use the equation rise / run.
So count how many boxes up and divide that number by the number of boxes across to find the slope.
Make sure that you are using exact point on the slope (where the dots are on the line) to make it easier to calculate.
Also start from the left-most dot (look at slope B example)
For example for the slope of A:
2 blocks up, 5 blocks to the right so the slope is 2/5
But for slope B, since the first dot is higher than the second dot:
5 blocks down (-5), 1 block right so the slope is -5/1 or just -5.
Answer:
C , D , B
Step-by-step explanation:
Trigonometry is given by three formulas :
SOH - CAH - TOA
- Sin x = Opp/Hyp
So Sine must be Option D - Cos x = Adj/Hyp
So Cosine must be Option C - Tan x = Opp/Adj
So tangent must be Option B
Hope this helped and have a good day
I believe the answer is:
