Answer:
72.9 degrees
Step-by-step explanation:
First we need to calculate the hypothenuse with the teorem of Pythagoras. ZY = sqrt(13^2+4^2) = 13.6 cm. sqrt stands for square root.
The we calculate the cosine of our angle (we could use the sine but I'll use the cosine here, the method is a little different with the sine). For the cosine divide the adjacent side by the hypothenuse: 4/13.6 =0.294
then we use the cos^-1 function on the calculator , so cos^-1(0.294) =72.897 =72.9 degrees.
I hope this helped
