70x+85(20-x)=1625
Solve for x
X=5 for 70
X=15 for 85
Since this is a right triangle and we have an angle and a side we can solve for any other side by using sohcahtoa. Now lets look at what we know we have the angle 35 degrees and the side adjacent to the angle is 10. we are looking for the side opposite to the angle. so we need a formula that uses opposite and adjacent that is toa, tan(angle)=oppisite/adjacent
now lets plug in tan(35)=x/10
x=10*tan(35)
x=7.002 now round to nearest tenth
x=7.0
78,000 rounded to the nearest ten thousand is 80,000.
Did you mean thousands? If you did the answer is <span>325,000
Happy studying ^_^
