Answer:
The value of a is 7.4833. The value of 
and 
.
Step-by-step explanation:
Consider the provided information.
The required figure is shown below:
We need to find the value of a.
Calculate the value of a by using Pythagorean theorem.
Hence, the value of a is 7.4833.
Now find the value of angle A as shown:
Find the value of angle B as shown:
Hence, the value of and .

Step-by-step explanation:
<u>Step 1: Identify Variables</u>
Angle = 35°
Opposite Leg = 3
Adjacent Leg = <em>x</em>
<em />
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [tangent]: tan35° = 3/x
- Multiply <em>x</em>: xtan35° = 3
- Isolate <em>x</em>: x = 3/tan35°
- Evaluate: x = 4.28444
- Round: x ≈ 4.3
