For this case we have two televisions, one generic version and one brand. We know that the generic version represents the size of the brand. We must define two variables that represent the dimensions of the brand TV, so we have:
- x: Brand TV length
- y: Brand TV width
Dimensions of the generic TV:
So:
By clearing the variables we have:
Thus, the dimensions of the brand TV are 18 inches by 36 inches
Answer:
The dimensions of the brand TV are 18 inches by 36 inches
Answer:
Step-by-step explanation:
As we are given the adjacent (a) side and the hypotenuse (h), we can use the cosine function to find the measure of angle B.
Recall that
This means that in order to find B, we need to take the inverse of cosine
This gives us
From a calculator, we find that the answer of this is
When this is rounded to the nearest hundredth, we get
