Please help. Find the value of x. Round to

Step-by-step explanation:

Find x

The relationship between x, 47 and $17^{\circ}$ is:

$sin(17^{\circ}) = \frac{x}{47}$

i.e.

$sin(\theta) = \frac{Opposite}{Hypotenuse}$

Solving further:

$sin(17^{\circ}) = \frac{x}{47}$

Make x the subject

$x = 47 * sin(17^{\circ})$

$x = 47 * 0.2924$

$x =13.7428$

<em></em> $x =13.7$ <em> --- approximated</em>

Solve for xxx. Give an exact answer. 0.5(5−7x)=8−(4x+6)

bearhunter [10]

Answer:

x=-1

Step-by-step explanation:

0.5(5−7x)=8−(4x+6)

I do not like working with fractions so I will multiply by 2 on each side

2*0.5(5−7x)=2*8−2(4x+6)

5 -7x = 16 -2( 4x+6)

Distribute

5-7x = 16 -8x -12

Combine like terms

5-7x =4-8x

Add 8x to each side

5 -7x+8x = 4-8x+8x

5+x = 4

Subtract 5 from each side

5-5+x = 4-5

x =-1
