If胃is an acute angle, solve the equation sin胃=12.

Short Answer

Expert verified

The solution is胃=30掳.

Step by step solution

01

Step 1. Given information 

Equation:sin胃=12

02

Step 2. Calculation 

Here 胃is an acute angle that is less than 90掳, so the angle is in the first quadrant.

Now, sin胃=12

胃=sin-112

胃=30掳
