Question

An equilateral triangle has perimeter 66. What is the length of its altitude?
A. 22
B. 22 square root 3
C. 11 square root 3
D. 11

Answer 1

equilateral means all same sides. and if it's perimeter (total) has 66. Then, one side must also be \(\sf \frac{66}{3}\)

Answer 2

so it'd be A?

Answer 3

its very simple..
square root of (33*33)-(16.5*16.5)

Answer 4

The answer comes lyk 28.57

Answer 5

but thats wrong.. considering its not even in the awnser choices

Answer 6

The altitude makes a right angle with one of the sides and half the base.
Use that and the fact that a side is 22, along with c^2=a^2 + b^2.

Answer 7

dear its not wrong u just need 2 do it in other form.... i'm new here so i'm not able to write it in an equation form... the basic is u need 2 first find the measure of one side and then use the pythagoras theorm

Answer 8

first do what abb0t says n then follow pythagoras..... draw a diagram u'll get it.

Answer 9

so its A

Answer 10

nope dear...
from the that you get 22 rite?
then u do this
22^2=11^2+height^2
solve this n u'll get it.. sorry my fist answer was wrong!
