3/4(12x−8)+3=10−1/2(6x+2)

Aleonysh [2.5K]

Answer:

$x=1$

Step-by-step explanation:

$\frac{3}{4}(12x-8)+3=10-\frac{1}{2}(6x+2)$

$(9x-6)+3=10-(3x+1)$

$9x-6+3=10-3x-1$

$9x-3=9-3x$

$9x=12-3x$

$12x=12$

$x=1$

Answer:

$75\sqrt{2}(\sqrt{3}-1)$

Step-by-step explanation:

In every right triangle, a leg is given by the multiplication of the sine of its opposite angle and the hypothenuse.

In this case, the opposite angle of x is 15°, and the hypothenuse is 300. So, we have

$x = 300\sin(15) = 75\sqrt{2}(\sqrt{3}-1)$

Tasya [4]

Answer:

k = 45*

2k = 90*

Step-by-step explanation:

K will be the same as the 45* degrees, as it is across from it.

2k is twice k, which is 90*.

45* + 45* + 90* = 180*

Good luck!
