Recall that tanA = sinA / cosA.
Therefore, tanA = (3/5) / (4/5) = 3/4.
We can use the substitution method to solve this problem.
The second equation is
, so we can plug in 2x for 'y' in the first equation:
Multiply:
Combine like terms:
This is the x-value of our solution, we can plug this into any of the two equations to find the y-value:
Multiply:
This is the y-value of our solution. So our entire solution is (3, 6).
a. true
b. false ( angles should equal 180 125+65=190)
c. true
d. true
e. true
