Ihave no idea how to calculate sinb can someone me? in advance.

bear in mind that, the opposite side to an angle, is the side that's "facing off" the angle, so if you put your "eye" on the ∡b, the side you'll see inside will be the "36" side, and the hypotenuse is always the slanted side, and the other is the adjacent side.

so depending on the angle, 36 is either opposite or adjacent, or 48 is opposite or adjacent.

Check the picture below.

a = 11 : 4

b = 38

c = 1 for every 6

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
