Answer:

x ≈ 28.8°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin x = $\frac{opposite}{hypotenuse}$ = $\frac{AB}{AC}$ = $\frac{3.9}{8.1}$ , then

x = $sin^{-1}$ ( $\frac{3.9}{8.1}$ ) ≈ 28.8° ( to the nearest tenth )

Select the correct choice that completes the sentence below.

vodomira [7]

$\sf \red⇛ \green {3a + 1 = 16}$

Move the constant to the right-hand side and change its sign to minus sign since it is in plus

$\sf \red⇛ \green{3a = 16 - 1}$

Subtract the numbers

$\sf\red ⇛ \green{3a = 15}$

Divide both sides of equation by 3

$\sf \red⇛ \green{a = 5}$

On observing the above steps, Option B is correct!
First step is subtraction then division
