The formula for area of triangle is -

________________________________
So, the area of first triangle =



________________________________
Area of second triangle =



________________________________
Area of second triangle - Area of first triangle



Answer:
you do 12 times 3 which equals 36 so 36 is your answer
Answer:
b, c, d are all false
Step-by-step explanation:
Let x=4, y=2. The given statement says ...
... -4 < -2 . . . . . a true statement.
Now, let's look at the answer choices.
... a. -4 < -2 . . . . true
... b. 2(4) < 2(2) . . . . false
... c. 4 +2 < 2 +2 . . . . false
... d. 4/2 < 2/2 . . . . false
Then "a" is true, and "b", "c", and "d" are false.
Answer:
1.)
≈ 3.652
2.) I would say something about how the A in front of cos in the equation would change to 90, rather than stay 75 (in the equation for the step by step), but it would be easier to just use the Pythagorean theorem.
Step-by-step explanation:
I think we may have the same class so hopefully this helps:
1.)
--> law of cosines formula.
--> plugged in numbers; when you draw the triangle, the included angle would be A, and the opposite side would be a. B and b, and C and c are opposite each other. In this case, a is the hypotenuse.
--> in between steps.
--> more simplifying.
--> answer
2.) This one is just an explanation: The 75 in the equation is the given angle, which is a. If this changes, it would just change in the equation too. And obviously, if it's 90 degrees, you can just use Pythagorean theorem a^2+b^2=c^2.
Good luck! :)
