Question on this?

Answer 1

Center at (0,0) r=8

Answer 2

I thought it was B but i got it wrong.

Answer 3

@vzfreakz do you have any idea on this?

Answer 4

Th

Answer 5

@HelloKitty/Trun what is that?

Answer 6

We can use the fact that We know 2 sides and an angle (instead of calculating the height of this triangle)

We want the area with angle A known so

\[\large Area = \frac{1}{2}bc \sin(A)\]

So we take the fact that A = 25
And both B and C are 20...and we make that equation

\[\large Area = \frac{1}{2}(20)(20) \sin(25)\]
\[\large Area = 200\sin(25)\]
\[\large Area = ?\]

Answer 7

Do you want to do it like that? Or would you like to have calculated the height and gone from there?

Answer 8

I'm extremely Lost to be honest with you
does the other way make more since?

Answer 9

Possibly :) lol

Alright...so we have



Right?

Answer 10

yeah the second picture

Answer 11

We know the area of a triangle is

\[\large \text{Area} = \frac{1}{2} \text{Base} \times \text{Height}\]

Answer 12

So we need to figure out the height...since we know that the base will be 20

Answer 13

Well, the height would be

Answer 14

Everything good so far?

Answer 15

yeah everything look just about right

Answer 16

Great...

Now...to find that height, we need to notice that



We have a right triangle
