Answer:
basic geometry and trig ratios
Step-by-step explanation:
sin 10 = 500/x
x = 500/sin 10
x = 2 879,4 m
I'm assuming you mean to list the terms of the expression. Those are mn, -2n, and +8. There are 3 terms there.

Sorry I don’t see the question how am supposed to answer it
Answer:
Given that,
In right triangle ABC, C is the right angle.
sin A=0.4
To find cos B,
we get the triangle as,
we know that,
Hypotenuse of the triangle is AB
For the angle A, opposite side is CB
For the angle B, adjacent side is CB
From the definition of sine and cosine we get,

Also,

Comparing both we get,

It is given that sinA=0.4
Hence we get, cosB=0.4
Answer is: 0.4
