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

The total tickets sold on Saturday was 50
The train station made 120
How many adult tickets and kid tickets did they sell?
(40 kids, 10 adults)
Given problem:
What is 9*5;
The formula P*Q = P x Q - 7;
To find 9*5, simply make P = 9 and Q = 5
Input into the equation and solve;
P*Q = P x Q - 7 = 9 x 5 - 7
= 45 - 7
= 38
The solution to this problem is 38.
