The answer is 7 1/2 becasue if you add the whole #s then the fractions you get the answer
A right angle is 90 degree, and all the three angles make a sum of 180, so the two acute angles will always add up to be 90
Answer: A) none of the equations are identities
==========================================
Part 1
Plug in theta = 0
sin(theta+pi/2) - cos(theta+pi/6) = 2*cos(theta) - sin(theta)
sin(0+pi/2) - cos(0+pi/6) = 2*cos(0) - sin(0)
1 - sqrt(3)/2 = 2*1 - 0
0.13 = 2
which is a false equation
So we do not have an identity in equation 1.
-------------------------------------------
Part 2
Plug in theta = 0
sin(theta+pi/6) + cos(theta+pi/3) = (sqrt(2)/3)*sin(theta) + 2*cos(theta)
sin(0+pi/6) + cos(0+pi/3) = (sqrt(2)/3)*sin(0) + 2*cos(0)
1/2 + 1/2 = 0 + 2
1 = 2
which is also false
This is not an identity either.
Well, 23 is a prime number, so that means that it only has two factors. 23 and 1. so the answer is 23 times 1
