Answer:
b. -36/77
Step-by-step explanation:
As 0 < x < 
/2 => tan x > 0
As 0< y < /2 => tan y > 0
We have the formula:
As tan x = 1/(cotx) => 
As tan x > 0 => tan x = 8/15
As tan y > 0 => tan y = 4/3
As tan (x-y)=

Answer:</h3>
a. -(3√13)/13
<h3>
Step-by-step explanation:</h3>
The cosine can be found from the tangent by way of the secant.
tan(θ)² +1 = sec(θ)² = 1/cos(θ)²
Then ...
cos(θ) = ±1/√(tan(θ)² +1)
The <em>cosine is negative in the second quadrant</em>, so we will choose that sign.
cos(θ) = -1/√((-2/3)² +1) = -1/√(4/9 +1) = -1/√(13/9)
cos(θ) = -3/√13 = -(3√13)/13 . . . . . matches your selection A
Answer:
(0, 2)
Step-by-step explanation:
Both the lines are intersecting each other at point (0, 2)
So, the solution to the system of equations would be (0, 2)
