Sin(79)/17 = sin(x)/12

kondaur [170]

Answer:

Step-by-step explanation:

We want to solve the equation $\frac{\sin(79)}{17}=\frac{\sin(x)}{12}$

We multiply through by 12 to obtain:

$\sin(x)=\frac{\sin(79)}{17}*12$

We simplify the RHS to obtain:

$\sin(x)=0.6929$

This implies that:

$x=\sin^{-1}(0.6929)$

$x=43.86\degree$

To the nearest degree, x=44 degrees

A sum of two mixed numbers is given. What is the missing number?

kaheart [24]

Answer:

16.

Step-by-step explanation:

The whole numbers stay the same so it stays as 2. The way they get 30 for the denominator is by multiplying the fraction 1/3 by 10 and 1/5 by 6. So now we have 10/30 and 6/30. Add them together, 10+6=16

Is the point (-2,5) a solution for the equation y = 10 + 4x. Explain why and ensure that math

Irina18 [472]

Answer:

No, the point (-2, 5) is not a solution.

Step-by-step explanation:

To see if the point is a solution, plug the given values for x and y into the equation:

y = 10 + 4x

5 = 10 + 4(-2)

5 = 10 - 8

5 $\neq$ 2

Because the two sides aren't equal to each, the point (-2, 5) can't be a solution.
