If the image is congruent to the pre-image, then the scale factor must be 1.
Answer:
Step-by-step explanation:
Given that:
and
To find:
Solution:
First of all,we have cos value as negative and tan value as positive.
It is possible in the 3rd quadrant only.
will lie in the 2nd quadrant so will be negative again.
Because Cosine is positive in 1st and 4th quadrant.
Formula:
Here
But as we have discussed, will be negative.
So, answer is:
To solve this problem, we just have to use trigonometric ratios and apply which of the ratios is needed here and proceed to solve. The value of side AC is 2.85 units
<h3>Trigonometric Ratio</h3>
In the given diagram, we have the value of angle and hypothenuse and we are required to find the adjacent side of the triangle.
Data;
- Angle = 32.9 degrees
- Hypothenuse = 3.4
Let's use cosine rule for this.
Proceed to substitute the values into the equation and solve.
From the calculations above, the value of side AC is 2.85 units
