Note: You can type the trig in the answer box for all these problems. For example if the answer is
50cos(10), you can just type that into the answer box. To get inverse trig functions type arcsin, arccos or
arctan.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb2cb3111-b82d-4ce1-a132-be48240451b0%2Fe1b8c86d-393e-4b8a-a770-f07978166a70%2F02qikva_processed.jpeg&w=3840&q=75)
