Step-by-step explanation:
a. the angle B in triangle ABC:
180-47=133°
angle C in ABC:
180-(40+133)=7°
using sine rule:
a/sin A= b/sin B= c/sin C
50/sin 7= BC/sin 40
BC= (50*sin40)/ sin7
=263.7 m
b.sin 47= opposite/hypotenuse
sin 47= CD/263.7
CD= sin 47*263.7
= 192.9
15% of 45 is 0.15 x 45 or 6.75 feet. That's how far the submarine descended in 1 minute. So, in 4 minutes the submarine would be 4 x 6.75 feet down which is 27 feet.
The key features of the graph include the fact the graphs are periodic.
<h3>How to illustrate the graph?</h3>
It should be noted that a graph is a diagram that represents ban interrelations between variables.
The tan graph is simply the visual representation of the tangent function for a range of angles.
In this case, the graphs have been attached and it can be seen that the tan graph repeats every 180° and is not a continuous curve.

Answer:
39°
Step-by-step explanation:
For a straight line, the sum of angle is 180°
At the point where we have the 107°, the inner angle in the triangle will be 180-107=73°
68° is alternate angle to the inner angle in the triangle
Since the sum of angles in a triangle are 180°, then angle x will be
X=180-73-68=39°
Therefore, missing angle is 39°
