An equilateral triangle has an altitude of 12.84 m. What is the
length of the three equal sides?

14.83m

Step-by-step explanation:

In an equilateral triangle, of side l and altitude h we have:

h=l/2×sqrt(3).

l=2h/sqrt(3)=2×12.84/1.73=14.83m

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

answer: 48
