Anyone help me out please?

? ≈ 52.3°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin ? = = , thus

? = ( ) ≈ 52.3° ( to the nearest tenth )

≈ 52.3

Step-by-step explanation:

You are given the opposite and hypotenuse side, leading you to use sin. However, since you're trying to find the angle measurement, you use the inverse of sin:

Set it up like this:

When you solve, you get:

52.34

Round to the nearest tenth:

52.3

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)

1/4 is the answer if i recall correctly.
