Since we know that t = 3.4 you put 3.4 where the t is.
2 (36 - 4 × 3.4) So what you do first is multiply 4 and 3.4 which gives you 13.6
2 (36 - 13.6) then you subtract 36 and 13.6 which gives you 22.4
2 (22.4) then you multiply 2 and 22.4 which is 44.8.
So your answer is 44.8

Answer:

Step-by-step explanation:
The sine of an angle is equal to the y coordinate point where the terminal side of the angle intersects the unit circle.
Its a right angled triangle. You have C and have B all you need to find is A. usually for a question like this you would use the Pythagorean theorem which is A2+B2=C2 but since we already have c we will use C2-B2=A2
Now we fill in the values. (21)2-(9)2=A2
441-81=360^2 so now with the 360^2 we have to squareroot it so the square root of 360 is 18.973f
