Answer:
Step-by-step explanation:11+12/square root of 16
11+(12/4)
11+3
answer is 14
The area of any triangle is (1/2) x (length of the base) x (height) .
In this problem, we know the triangle's height,
but what is the length of the base ?
The base is the side that the triangle is sitting on. This particular triangle
is an equilateral one, and its perimeter is 60m. So each side must be 20m.
No matter which side the triangle is sitting on, the length of the base is 20m.
Area = (1/2) x (base) x (height)
Area = (1/2) x (20m) x (17.3m) = <em>173 m²</em>
<span>the approximate measure of the largest angle in the triangle is 75.5 degrees</span>
your answer would be 13.5
