Question

An equilateral triangle with side length 14 cm is shown in the diagram, work out the height of the triangle.

Answer 1

Answer:

length of all sides =14cm

Step-by-step explanation:

let height be X

length of base =7cm

therefore x^2+7^2=14^2

x^2+49=196

x^2=196-49

x^2=147

X=√147

X=12.247
