Answer:
A=61.99°
Step-by-step explanation:
sin A = 0.8829
To solve for A, all you need to do is to take the sin⁻¹ of both-side
That is;
sin⁻¹sin A = sin⁻¹0.8829
At the left-hand side of the equation, sin⁻¹ will cancel-out sin leaving us with just A while at the right-hand side of the equation, we need to take the sin⁻¹ of 0.8829. To do that we need to use the calculator
A =sin⁻¹0.8829
You will press shift then sin in your calculator, then write 0.8829 and then press the equal sign
A=61.99°
