Answer:
Area= 50√3 units^2
Step-by-step explanation:
Given:
In given triangle, there are two sides with length 10√3 and 20 along with angle of 30° between them.
As the given triangle is SAS triangle, we'll use the following formula to calculate its area:
A=1/2absinC
where a= 20
b= 10√3
and c=30°
Now putting values we get:
A=(1/2)(20)(10√3) sin(30)
=100√3(1/2)
=50√3
so the area is 50√3 units^2 !
I don't know what the "act it out" strategy is but I will try to help based on my knowledge.
Try this: Write down the numbers 1-4. Then make number combinations with 3 of those 4 numbers. See how many you can make with out repeating a combination. Even it is in a different order. How ever many combinations you can mane is your answer.
This is how I would do it.
Let me know if this helps or not.
Good Luck
Solve for x
6x+5y=-15
subtract 6x from both sides
5y=-6x-15
divide both sides by 5
y=-6/5x-3
In this order
500
250
25,000
The answer is 7859
I did it and got it right.....
