Round to the nearest hundredth please in the final answer

Answer 1

see the attached figure below to better understand the problem

In this problem, we have an isosceles triangle

the measure of the other two interior angles are

2A+64 10'=180

2A=115 50'

115 50'------> convert to degrees

115+50/60=115.83 degrees

2A=115.83

A=57.92 degrees

Now we have the right triangle

tan(57.92)=x/2.100

x=2.100*tan(57.92)

x=3.35 in
