Answer:
5 over 3 is the slope
(0,4/3) is the y- intercept
Step-by-step explanation:
move the 3 to the 7 side. it will become negative.
9x-5x=7-3
4x=4
x=1
Reflecting over y=x results
(2,4)
8 and 15 are the lengths of the legs.
The tangent is the ratio of the lengths of legs.
In general, tan x = opp/adj
You have 8/15, so here 8 is the opposite leg and 15 is the adjacent leg.
Angle A is the right angle, so that is not it.
For which acute angle, B or C, is 8 opposite and 15 adjacent?
Answer: for angle B.
Therefore, 8/15 must be tan B.
