Answer:
x = 53/6 , y = -55/6
Step-by-step explanation:
Let the 2 numbers be x and y.
x+y = -1/3 ........... (1)
x-y = 18...............(2)
This is a simultaneous equation we will use elimination method.
Add equation 1 and 2
2x = 18 - ⅓
2x = 17⅔
2x = 53/3
Multiply both sides by 3
6x = 53
Divide both sides by 6
x = 53/6
Put x = 53/6 into equation 1
x+y = -⅓
53/6 + y = - ⅓
y = -⅓ - 53/6
y = -55/6
Therefore x = 53/6 , y = -55/6

Answer: C) tan(pi/56)
=============================================
Explanation:
I recommend using a trig identity reference sheet. The specific identity we will be using is
What we are given is in the form with A = pi/7 and B = pi/8
A-B = (pi/7)-(pi/8)
A-B = pi(1/7-1/8)
A-B = pi(8/56 - 7/56)
A-B = pi*(1/56)
A-B = pi/56
Therefore,
A diagram lime this would prove, as shown above the opposite angles are equal.
