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

Since we know that all angles in a triangle add up to , we can solve for
and substitute it back into
to find
.
Remove the parentheses and combine like terms.
Add to both sides of the equation.
Divide both sides of the equation by .
Now that we have the value of , we can substitute it back into
to find
