A triangular pyramid has 3 rectangular sides and a top and bottom triangular base.
Without using a calculator I would say the root is between 10 and 11
How I found the answer:
I know 10 * 10 = 100
I know 11 * 11 = 121
So the root of 100 = 10 and the root of 121 = 11 so that means the root of 108 is somewhere between 10 and 11, which the root of 108 = 10.3923
Answer:
ED ≈ 2.6 units
Step-by-step explanation:
Using the Sine rule in Δ DEF
= 
=
( cross- multiply )
ED sin115° = 6.95 sin20° ( divide both sides by sin115° )
ED =
≈ 2.6 ( to the nearest tenth )
