Sorry I made a mistake here. Instead of 0.974 the answer should be 1.34. Thx to the person who pointed it out.

Hi. This is another approach for your consideration. To go about the question, apply the appropriate 'changing of trigonometric identity' property and you should be good to solve for the value of theta. The question test on the use of R-Formulae or Trigonometric Changing Identity concept or other concepts. The first tutor approach is unique. However one of the answers of theta is wrong. I suggest the tutor to check again. Thanks.

*The question test you on the use of R-Formulae or Changing of Trigonometric Identity concept primarily. Other concepts can be used where applicable.*
Thx for pointing out my mistake. It was due to me pressing the calculator wrongly.
Sure no worries. :)
