Question 1073722: In a right triangle ABC, the length of hapotanous is 1 m and one of the angle is 15 degree then find the area of the triangle. Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! The other angle is 90 - 15 = 85 degrees
:
sin(15) = AB(height) / 1
:
height = sin(15) * 1 = 0.2588 m
:
sin(85) = AC(base) / 1
:
base = sin(85) * 1 = 0.9962 m
:
***********************************************************
Area of triangle ABC = (1/2) * 0.9962 * 0.2588 = 0.1289 m^2
