Answer:

8

Step-by-step explanation:

sin theta = opposite side/ hypotenuse

sin 30 = 4/x

Multiply each side by x

x sin 30 = 4

Divide each side by sin 30

x sin 30 /sin 30 = 4 sin 30

x = 4 /sin 30

We know that sin 30 = 1/2

x = 4 / 1/2

x = 8

For this case we have to, by trigonometric properties applied to rectangular triangles:

Sine (30) = \frac {Cathet \ opposite} {Hypotenuse}\\Sine (30) = \frac {4} {x}

Clearing x:

x = \frac {4} {Sine (30)}\\x = \frac {4} {\frac {1} {2}}\\x = 8

Thus, the value of the hypotenuse is 8.

Answer:

x = 8

marissa [1.9K]
To answer the question above, isolate F on the other side of the equation by multiplying both sides by 9/5. This gives, 
                           (9/5) C = F - 32
Next, transpose -32 to left side. 
                            (9/5)C + 32 = F
Rearrange the equation to give an answer of
                              F = (9/5)C + 32
