Answer:
The answer would be x=7.3 cm
Step-by-step explanation:
Since you are using the angle of 20 degrees and you have the measure of 10 cm for its adjacent side, solving for x would mean you would use tan.
20=x/10
10*20tan=x
200tan=x
7.279404......=x
But when you do 200 tan on the calculator, you have to make sure you press the equal sign after.
