Answer:

$y = 52.02$

Step-by-step explanation:

Given

The attached triangle

Required

Find y

Taking y as a reference , we have:

$Adjacent = 8$

$Hypotenuse = 13$

So:

$\cos(y) = \frac{Adjacent}{Hypotenuse}$

This gives

$\cos(y) = \frac{8}{13}$

$\cos(y) = 0.6154$

Take arccos of both sides

$y = \cos^{-1}(0.6154)$

$y = 52.02$

-15 + 12x = 5x + 7 -3x<br> SOLVE FOR X

Natali [406]

Answer: $x=\frac{11}{5}$

<u>Simplify both sides of the equation</u>

<u></u> $-15+12x=5x+7+-3x$ <u></u>

<u></u> $12x-15=(5x+-3x)+(7)$ (Combine Like Terms)

$12x-15=2x+7$

<u>Subtract 2x from both sides</u>

<u></u> $12x-15-2x=2x+7-2x\\10x-15=7$ <u></u>

<u></u>

<u>Divide both sides by 10</u>

<u></u> $\frac{10x}{10} =\frac{22}{10}$ <u></u>

<u></u> $x=\frac{11}{5}$ <u></u>

<u></u>
