Answer 1

Triangle JMN is an equilateral triangle of side 10.
The distance from J to segment MN is the same as the length of the red altitude drawn from M to segment MN in triangle JMN.

Answer 2

so.. I need to find the altitude?

Answer 3

is it just the same length.. which is 10?

Answer 4

The altitude drawn to the base of this triangle bisects the base.
You can find the altitude using the 30-60-90 theorem or by using the Pythagorean Theorem.

** The answer is not 10.

Answer 5

oh, pythagorean? alright.. :)

Answer 6

You can crank out:

10² = 5² + h²

Solve for h.

Answer 7

Or, you can apply the 30-60-90 theorem

Answer 8

5(sqrt3)
or 8.55
am i right?

Answer 9

>>>>5(sqrt3) or 8.55

5 SQR(3) is 8.66 approx

Answer 10

oh right ,another typo .__.
thank youuu :D
