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.

7 1/2 miles
Step-by-step explanation:
The distance to the airport is 10 miles
The distance to the lake is 3/4 the distance to the airport
d =3/4 *10
d =30/4 = 7 2/4 = 7 1/2 miles
Each of 4 friends has 2 balloons 4 x 2 = 8 herself has one so 8 + 1 = 9 answer: Total 9 balloons
2x + 3*6 = 36
2x = 36-18
2x = 18
x = 9
