Answer:

-2

Step-by-step explanation:

6-8x=5x-10x+12

5x-10x=-5x

=6-8x=-5x+12 MOVE -5x TO THE LEFT SIDE AND 6 TO THE RIGHT SIDE

= -8x+5x=12-6

= -3x=6

= -x=2

= x=-2

Answer:

I guess it's -2

Step-by-step explanation:

6-8x = 5x - 10x + 12

∴ 10x - 8x - 5x = 12 - 6

∴ 10x- 13x = 6

∴ - 3x = 6

∴ x = -6\3

∴ x = -2

Use law of sines or law of cosines to find the length of side AB Please show work !!

scoray [572]

Answer:

$AB = 11.3$

Step-by-step explanation:

Given

The attached triangle

Required

Length AB

To do this, we make use of sine law which is represented as:

$\frac{a}{\sin(a)} = \frac{b}{\sin(b)} = \frac{c}{\sin(c)}$

So, we have:

$\frac{15}{\sin(70)} = \frac{AB}{\sin(45)}$

Make AB the subject

$AB = \frac{15}{\sin(70)} * \sin(45)$

$AB = \frac{15}{0.9397} *0.7071$

$AB = 11.3$
