Olin [163]

Answer:

\frac{2}{15}

Step-by-step explanation:

Substitute the values for a and c into the expression

- 2c + a

= - 2× \frac{3}{10} + \frac{11}{15}

= - \frac{3}{5} + \frac{11}{15}

= - \frac{3(3)}{5(3)} + \frac{11}{15}

= - \frac{9}{15} + \frac{11}{15}

= \frac{2}{15}

Answer:

\Huge\boxed{D.14.6}

Step-by-step explanation:

Hello There!

We can solve for x using trigonometry

More specifically the law of sines

In the image you can see that a side length divided by sin(its opposite angle) is equal to another side length divided by sin(its opposite angle)

so to find x we use this equation

\frac{x}{sin59} =\frac{17}{sin90}

step 1 multiply each side by sin 59

now we have

x=\frac{17sin59}{sin90}\\x = 14.6

so we can conclude that x = 14.6

SOMEONE PLEASE HELP!
Andrews [41]

Answer:

17.2°

Explanations

To find angle A, use the cosine rule.

a^2 = b^2 + c^2 - 2 × a × c cos A

4^2 = 7^2 + 10^2 - 2 × 7 × 10 cos A

16 = 49+ 100 - 140 × cosA

16 = 149 - 140cosA

16- 149 = - 140cosA

-133 = - 140cosA

cosA = 133/140

cosA = 0.95

A = 17.2°
