Sin 20 is the answer
Using the trigonometry rule
Sin cos tan
Sin x = opposite side (a) / hypotenuse side (c)
A/c = sin x
x= 20 ( angle formed by side c and b )
Answer:
Did you copy this down correctly?
Step-by-step explanation:
b = .125 which is rational
a is irrational because the square root of a prime number is irrational.
If c = 225....
then adding 2 rational numbers = rational sum
But adding (or multiplying) an irrational number to a rational number = irrational number.
D. 3 since one vertex always face 2 vertex that you can draw a diagonal line with, its going to divide the pentagon to 3 different area which form 3 triangles
