So hmm notice the picture below

thus $\bf \cfrac{y}{tan(64^o)}=\cfrac{y}{tan(46^o)}-100\implies 
\cfrac{y}{tan(64^o)}-\cfrac{y}{tan(46^o)}=-100
\\\\\\
y\left[ \cfrac{1}{tan(64^o)}-\cfrac{1}{tan(46^o)} \right]=-100\implies y=\cfrac{-100}{\frac{1}{tan(64^o)}-\frac{1}{tan(46^o)}}$

make sure your calculator is in Degree mode, since the angles are in degrees

What is 63.5% written as a decimal? A. 0.0635 B. 0.635 C. 6.35 D. 635

Answer:

B. 0.635

Step-by-step explanation:

Having a percent means its out of 100 so we can turn the percent into a fraction. 63.5/100

We cant have a decimal in our fraction, so we can multiply by 10 to get rid of it. (63.5*10)/(100*10)=635/1000

Since the denominator is a multiply of 10, we can convert the numerator into a decimal. .635

So your answer would be B. 0.635
