Help please please <br> $)

<h3>Look at the picture.</h3>

<em>commutative property</em>  a + b = b + a

... (-5 + 1/2 + 5) = ... (-5 + 5 + 1/2)

<em>inverse property of addition</em> a + (-a) = a - a = 0

... (-5 + 5 + 1/2) = ... (0 + 1/2)

<em>identity property of addition</em> a + 0 = 0 + a = a

... (0 + 1/2) = ... 1/2

<em>inverse property of multiplication</em> a/b · b/a = 1

37 · 2 · 1/2 = 37 · 2/1 · 1/2 = 37 · 1

<em>identity property of multiplication</em> a · 1 = 1 · a = a

37 · 1 = 37

Find the value of x. Round to the nearest tenth.please help.
Serga [27]

Answer:

39.9

Step-by-step explanation:

A good trick to remember is SOH CAH TOA.

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

Here, we're given an angle and the opposite side, and we want to find the adjacent side.  So we need to use tangent.

tan 31° = 24 / x

x = 24 / tan 31°

x ≈ 39.9
