Answer:
9
in²
Step-by-step explanation:
The area (A) of an equilateral triangle is calculated as
A =
( s is the length of a side )
Here s = 6, thus
A =
=
= 9
in²
Answer:
c and d
Step-by-step explanation:
The answer to this problem would be 2.5.
Answer:
Step-by-step explanation:
<u>The ratio of sides in 30º-60º-90º triangle is:</u>
<u>If a is 5√3, the length of b is:</u>
- b = a√3 = 5√3 *√3 = 5*3 = 15
A3=3
a4=5
a5=8
This sequence has properties similar to those of the Fibonacci sequence.
