substitute the given values

tan(R)=\frac{8}{3}

using a calculator

m\angle R=tan^{-1}(\frac{8}{3})=69.4^o

A 12 foot ladder is placed 4 feet away from a house as shown. What is the value of x, rounded to the nearest degree ?
Otrada [13]
This is a sohcahtoa question, in this case itd be cosine. The "cah" part stands for cos(x)=adjacent/hypotenuse. Using numbers it would be cos(x)=4/12. To find x youd have to take the cos^-1 of both sides so x=cos^-1(4/12)
