Question

What is the C.G of an isosceles triangle of base 20 cm and side 40? *

1 point

a. 12.90 cm

b. 13.28 cm

c. 19.36 cm​

Answer 1

Step-by-step explanation:

c. 12.90 because centre of gravity of an isosceles triangle is centroid of triangle and its formula is √(4*side2-base2)/6

Answer 2

Answer:

a) 12.90 cm

Step-by-step explanation:

given:

base=20 cm

side=40 cm

to find the

Centroid(C.G) = Height of isosceles triangle (h) / 3

height of the triangle(h)

=$\sqrt{40^2-10^2}$

=$\sqrt{1600-100}$

=$\sqrt{1500}$

=38.72 cm

centroid=h/3

             = 38.72/3

             = 12.90cm
