Using the cosine rule, the equation to use to solve for x is: x = √(4.0² + 4.7² − 2(4.0)(4.7) × cos(41)) ≈ 3.1 cm.
<h3>How to Use the Cosines Rule to Solve a Triangle?</h3>
The cosine rule is given as, c = √(a² + b² − 2ab × cos(C))
Given the following:
- c = x = ?
- a = 4.0 cm
- b = 4.7 cm
- C = 41°
Plug in the values:
x = √(4.0² + 4.7² − 2(4.0)(4.7) × cos(41))
x ≈ 3.1 cm

Perimeter = 2(length) + 2(width)
= 2(35) + 2(25)
= 70 + 50
= 120
Answer: 120 meters
Answer:
See explanation.
Step-by-step explanation:
<u>Aim of experiment:</u>
To discover the amount of time (average amount of time) that 7th grade students spend on homework each week.
<u>Name of researcher:</u>
Mary.
<u>Requirements for the experiment:</u>
- knowledge of the number of hours that some or all of the students spend on homework each week
- knowledge of the total number of 7th grade students (population statistics)
<u>The issue or problem with this question </u>is that it doesn't say what Mary found out after her research. There are no result statistics from the experiment! Mary surveyed 20 students out of the 164. Her findings will/can be used to infer about the population. Those findings are absent here, hence the question can't be solved.

To help you get started: Add together the monthly payments. Divide this sum by the given gross income. Here we'd get $1000/$4500, or 10/45, or 22.2%, and Tran's remaining income after debts would be $4500-$1000 = $3500.
You will have to review your class notes and/or textbook to determine "the largest piti for which he could qualify," based upon these figures.
