Question

Which equation can be used to solve for b? b = (8)tan(30o) b = b = (8)sin(30o) b =

Answer 1

the answer is
tan30 = b/8
b=8tan30

Answer 2

In a right angle triangle the three sides are represented by the letters a, b and c .

a represents the side adjacent with given angle .

b represents the side opposite to the given angle.

c represents the hypotenuse of the triangle .

Check the attached image for clear picture of the right angle triangle with angle 30 degrees .

Using the trigonometric ratio we can write the ratio as

`(b)/(a) = tan(30^0)`

Multiplying both sides by a , we get

`b =a * tan(30^0)`

since a=8 so

`b = 8* tan(30^0)`
