What is the answer to 19=-3a-5

stepan [7]

Answer:

$\fbox{ \huge{ \sf{ a = - 8}}}$

Step-by-step explanation:

$\bigstar{ \sf{ \: 19 = - 3a - 5}}$

$\tt{Step \: 1 \: }$ : Swap the sides of the equation

$\longmapsto{ \sf{ - 3a - 5 = 19}}$

$\tt{Step \: 2 \: }$ : Move 5 to right hand side and change it's sign

$\longmapsto{ \sf{ - 3a = 19 + 5}}$

$\tt{Step \: 3 \: }$ : Add the numbers : 19 and 5

$\longmapsto{ \sf{ - 3a = 24}}$

$\tt{Step \: 4 \: }$ : Divide both sides by -3

$\longmapsto{ \sf{ \frac{ - 3a}{ - 3} = \frac{24}{ - 3}}}$

$\tt{Step \: 4}$ : Calculate

$\longmapsto{ \sf{a = - 8}}$

$\sf ∴ \: the \: value \: of \: a \: is \: - 8.$

Find side x , give your answer 1 decimal place <br>

Vladimir [108]

<u>Given</u>:

Let A denote the angle of the given triangle which measures ∠A = 81°

Let B denote the angle which measures ∠B = 40°

The length of the side a = x.

The length of the side b = 7 cm.

We need to determine the value of x.

<u>Value of x:</u>

The value of x can be determined using the law of sine formula.

Applying the law of sine, we have;

$\frac{sin \ A}{a}=\frac{sin \ B}{b}$

Substituting the values, we have;

$\frac{sin \ 81^{\circ}}{x}=\frac{sin \ 40^{\circ}}{7}$

Simplifying, we get;

$\frac{0.988}{x}=\frac{0.643}{7}$

Cross multiplying, we have;

$0.988 \times 7=0.643 x$

$6.916=0.643x$

$10.8=x$

Thus, the length of the side x is 10.8 cm.
