Question

Easy math please help!

Answer 1

`\boxed{ \sf 41.81}`

Explanation:

The triangle is a right triangle.

We can use trigonometric functions.

`\sf sin(\theta)=(opposite)/(hypotenuse)`

`\sf sin(?)=(2)/(3)`

`\sf ?=sin^(-1)((2)/(3))`

`\sf ?= 41.81031489...`

Answer 2

`\boxed{41.81}`

Explanation:

∠B is opposite of side AC, which has a length of 2 units. The hypotenuse of the triangle is equivalent to 3 units.

The trigonometric function that uses the opposite side and the hypotenuse is sine function. This is represented by
`sin = (opposite)/(hypotenuse)`. The side that is opposite to the angle being solved for is the opposite side (it does not border the angle and it is not the hypotenuse).

However, you are solving for an angle. So, you need to use the inverse sine function (
`sin^(-1)`) to solve this question properly.

Simply type into a calculator
`sin^(-1) ((2)/(3))` and it will evaluate the answer to approximately 41.81°.
