Answer:
The missing value is 2.9mm and cosine was used
Step-by-step explanation:
Given triangle is a right-angled triangle we can use trigonometric ratios to calculate the missing length.
In the given triangle,
Base = k
Hypotenuse = 15mm
Angle = 79
We will use trigonometric ratio which includes base and hypotenuse.
Using cosine,
Rounding off to nearest tenth
Hence,
The missing value is 2.9mm and cosine was used
Using proportions, it is found that each person consumes 3.57 times as many rice in Brazil and they do in the United States.
<h3>What is a proportion?</h3>A proportion is a fraction of a total amount.
In this problem, we have that:
- The rate in Brazil is of
.
- The rate in the United States is of
.
Hence, the rate between the consumption in Brazil and in the United States is given by:
Each person consumes 3.57 times as many rice in Brazil and they do in the United States.
