What is the length of the altitude of the equilateral triangle below
1 answer:
Using Sine.
Sine = Opposite / Hypotenuse
sin 60° = a / (6√3) But sin60° = √3/2
√3/2 = a/(6√3)
Cross multiply
2*a = 6√3 * √3
2a = 6 * √(3*3)
2a = 6*3
a = 6*3/2
a = 3*3 = 9
Option E.
Hope this helps.

3/5 x 7/7= 21/35
4/7x 5/5= 20/35
They both have a common denominator
3 X 3 = 9
9 X 2 = 18
5 X 8 = 40
40 X 2 = 80
80 + 18 = 98
98 is your answer
