Thanks for reply. So Ive done the first 3 questions. For question 'd' i am confused, because there is no any labeled angles in the triangle. I know AM is 30, and i tried use S=ab sinC to solve the area, however, it is not possible without angle.

Hi EMD. There's another area formula for triangles.

Area = 1/2 * Base * Height

That's okay. All human animals are "dumb", from time to time.

(I walked into a telephone pole last week.)

If I understand the notation correctly the coordinates [imath]R:\left(10,5\sqrt{5}\right)[/imath]
If that is correct then the height of [imath]\Delta MAR[/imath] is [imath]5\sqrt{5}[/imath]. WHY?
What is the length of the base [imath]\overline{MA}~?[/imath] What is the area?
