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:
x = 1
y = 2
Step-by-step explanation:
y =8x - 6 ---------------------------------(I)
y = 2x -------------------------------------(II)
substitute y = 2x in equation (I)
2x = 8x - 6
Add 6 to both sides
2x + 6 = 8x
Subtract 2x from both sides
6 = 8x - 2x
6 = 6x
Divide both sides by 6
6/6 = x
x = 1
Substitute x = 1 in equation (II)
y = 2*1
y = 2
-31/15 is the correct answer
