Question

4. if each side of an equilateral triangle is 10 cm, find the altitude and area of the
triangle ( 3 = 1.732).​

Answer 1

Answer:

altitude = 8.66

area = 43.3

Step-by-step explanation:

altitude of equilateral triangle can be found by using Pythagoras theorem

so 1/2 base = 5

and hypotenuse = 10

so altitude = 5^2 + x^2 = 100

altitude = 5√3 = 8.66

area = 1/2 * b * h

area = 1/2 * 10 * 8.66 = 43.3
