Answer:

64.8

Step-by-step explanation:

first you draw out the problem and label the sides of the triangle. since you are finding an angle you use the -1. so looking at the triangle you know that it will be Tan^-1 (Opposite/adjacent). so you write the problem

tan^-1(850/400)= 64.79887635

rounded to the nearest tenth would equal

64.8.

so your answer is 64.8.

Hope this helps! :)
