Best ResponseYou've already chosen the best response.2first you would need to find the area of the rectangle. Then you would find the area of the triangle with the formula A = 1/2 B H. To find the height you would need to sin rule.

Best ResponseYou've already chosen the best response.2if you used the sin rule the length opposite 60 is \[\sqrt{48}\]

Best ResponseYou've already chosen the best response.2they want the area of this question right?

Best ResponseYou've already chosen the best response.2if you used the sin rule again you would find the bottom length to be equal to 4.

Best ResponseYou've already chosen the best response.2so the area of the triangle is equal to 8 root 3. \[8\sqrt{3}\]

Best ResponseYou've already chosen the best response.2ok.. the area of the traingle is 1/2 b h right? 1/2 * 4 * \[\sqrt{48}\] I have gotten this by using right angle trig? sin cos tan?

Best ResponseYou've already chosen the best response.21/2 * 4 * \[\sqrt{48}\] = \[\sqrt{192}\] which is simplified to be\[8\sqrt{3}\]

Best ResponseYou've already chosen the best response.0so now i know that whats next?

Best ResponseYou've already chosen the best response.2well i got the area of the triangle so all you need now is area of rectangle and add them together

Best ResponseYou've already chosen the best response.2and sorry this has nothing to do with special triangles

Best ResponseYou've already chosen the best response.2ill complete it for you... (hope you can understand this) the bottom of the rectangle is equal to 6 ( 104) the length is \[\sqrt{48}\] so its \[\sqrt{48}\] * 6 which is \[24\sqrt{3}\] so now we add these area together which is \[32\sqrt{3}\]

Best ResponseYou've already chosen the best response.0i thought the bottom rectangle was 4?

Best ResponseYou've already chosen the best response.2It says on the diagram the whole length which is the triangle and rectangle is equal to 10. The bottom of the triangle is 4. So the rectangle is 104. which is 6
