In ΔDEF, the measure of ∠F=90°, DF = 55, FE = 48, and ED = 73. What ratio represents the tangent of ∠D?
1 answer:
Answer:
Step-by-step explanation:
In problems like this, it always helps to draw a picture.
-> See attached for the picture I drew (<em>not to scale</em>)
Now, the trigonometric function tangent can be found with opposite / adjacent
When looking at ∠D, the opposite side if 48 and the adjacent side is 55.
O / A = 48 / 55

Answer:
2 is the correct option.
Step-by-step explanation:
We have the equation .
We will plot the graphs of the function and
.
Then, the intersection points of both the graph will be the solution of the equation .
From the graphs, we see that,
The intersection points of the graphs are (0,1) and (2.337,10.347).
The solution of the equation is the value of 'x' co-ordinate where they intersect.
So, we get, x = 2 is the correct option.
