Answer:
The exact value of 
is 
.
Step-by-step explanation:
Recall that is a special angle that can be obtained using an equilateral triangle.
The right triangle obtained using one of the lines symmetry was used to find the exact value of using SOH-CAH-TOA
The exact value of is .
There are 12 white ribbons, 15 red ribbons, and 11 blue ribbons.
38=(w-1)+(w+3)+w
combine like terms
38=2+3w
subtract 2 from both sides
36=3w
divide 3 on both sides
12=w
w-1=b
12-1=b
11=b
w+3=r
12+3=r
15=r
Check Your Work
w+r+b=38
15+11+12=38
38=38

a=4 and b=6.
so you will plug the 4 for a and plug 6 in for b
the new equation is going to be:
3(4)-(6)
3*4-6
12-6
THE ANSWER IS 6
