An isosceles triangle has an area of 32 cm2, and the angle between the two equal sides is 5π/6. Find the length of the two equal sides. (Round your answer to one decimal place.)
1 answer:
The area of a triangle can be determined by knowing 2 sides and their included angle of a certain triangle. Since both sides are equal, then they would just be denoted by a squared entity. This is done as follows: A = x² sin∅ 32 = x² sin (5*pi/6) Make sure your calculator is in rad form. 32 = x² (1/2) x = 8 Thus, each side is 8 cm.
