Answer:
110.98 m
Step-by-step explanation:
you have a right triangle and you know the adjacent side to the 25 degree angle and are looking for the opposite side of the angle
tan of an angle = opposite side/adjacent side
Let d = depth of submarine
So, tan 25 = d/238
238 tan 25 = d
d = 110.98 m
Note: You must memorize the definitions of all the trig functions and then these types of problems will be easy. OK?
Answer:
y=-1/4x-1/2
Step-by-step explanation:
When two lines are parallel, they have the same slope.
So for this line, we already know that the slope (m) has to equal -1/4x.
Slope intercept form is y=mx+b, where m is the slope and b is the y intercept.
in order to find the equation, we must plug in x and y to solve for b, the y intercept (the value of y when x=0).
Now, let's plug in 2 for x and -1 for y and solve for b:
-1=-1/4(2)+b=-1=-1/2+b=-1+1/2=b
b=-1/2
Hence, the answer is y=-1/4x-1/2
Answer:
C) 5x-70=105
Step-by-step explanation:
As marked in the graph, angle 105 and angle (5x-70) equal to each other because they are vertically opposite angles therefore we have equation C)
