Final answer:
To solve 2.9 cos 17 rounded to 2dp, the calculation gives a result of approximately 2.77.
Step-by-step explanation:
The question involves calculating the value of 2.9 cos 17 and then rounding the result to two decimal places (2dp).
Assuming the angle is in degrees, this is a trigonometry calculation, and the following steps are taken:
- First, use a calculator to find the cosine of 17 degrees.
- Then, multiply the result by 2.9.
- Lastly, round this product to two decimal places.
Cosine of 17 degrees (cos(17)) might be approximately 0.9563.
Multiplying this by 2.9 gives 2.77347, which when rounded to two decimal places is 2.77.
