The altitude of an equilateral triangle is 15.
In order for us to get the area of the equilateral triangle, we need to find the formula first.
Area = square root of (3) / 4 * a^2
Area = square root of (3) / 4 * 15^2
Area = 97.42786 square units.
<span>So the area of the equilateral triangle given the altitude 15 is 97.43 square units.</span>
3/4 is 2x bigger than 3/8.

Answer:
140 degrees.
Step-by-step explanation:
Because BD is a tangent to the circle the angle ABD = 90 degrees.
So m < BAD = 180 - 90 - 50
= 180 - 140 = 40 degrees. ( as there is 180 degrees in a triangle).
So m < BAF = 180 - 40 = 140 degrees (adjacent angles).
I am certain the answer is A and D. Plze mark me brainiest:)
