In some trigonometry classes, this acronym is very important to solving questions like this.
Why?
It tells us the right triangle-definition of these trigonometry functions.
We have that cosine of an angle is equal to tge side that is adjacent to it over the hypotenuse.
So here we are asked to find cos(B).
Lets look at triangle respect to the angle B
The measurement of the side that is opposite is 64.
The measurement of the side that is adjacent is 48.
The measurement of the hypotenuse is 80.
So cos(B)=48/80.
Let's reduce. 48 and 80 have a common factor of 8 so divide numerator and dexter by 8. This gives us:
cos(B)=6/10.
One more step in reducing. Both factors are even so cos(B)=3/5.

Answer:
The cost of 12 gallons of gas and a quart of oil is 14·x - 30
Step-by-step explanation:
When adding variables, the coefficient of the variables are added followed by multiplication of the sum of the coefficients with variable as follows;
The cost of 12 gallons of gas = 12·x
The cost of a quart of oil is represented by 2·x - 30
Therefore, the cost of 12 gallons of gas and a quart of oil can be represented as follows;
12 gallons of gas and a quart of oil = 12·x + 2·x - 30
Which gives;
The cost of 12 gallons of gas and a quart of oil = 14·x - 30.
Find 20% of 240.
Of means to multiply.
20% has to be changed to a decimal.
.20 * 240 = 48
Answer:
The answer is c
Step-by-step explanation:
negative degrees below zero is like two negative which equals a positive so in other wourd it would be the same as 10 degrees above zero
its c
