Find the measure of angle x in the figure below:

Kipish [7]

The three angles on top are supplementar. This means that

$56+y+51 = 107+y = 180 \implies y = 180-107 = 73$

So, the angles of the triangle are x, 72 and 73. Again, we know that the sum of the interior angles of a triangle is 180, so we have something similas as before:

$72+x+73 = 145+x = 180 \implies y = 180-145 = 35$

So, the measure of angle x is 35.

Triangle P=27,Q=40,P=33 law of sines round measures to the nearest tenth

nordsb [41]

For the law of sines, you would apply it in this particular problem like so:
Since P is 27, its angle is 33 and Q's length is 40; you would set it up like this
<u />40/SinQ = 27/Sin33, multiply 40 with Sin33, then it would be 40Sin33, then divide it by 27. The result should be 40Sin33/27 = X

Find the solution of this system of equations 10x-7y=-1 and -2x-7y=-25

Sergio039 [100]

Answer:

Step-by-step explanation:

$\left\{\begin{array}{ccc}10x-7y=-1\\-2x-7y=-25&\text{change the signs}\end{array}\right\\\underline{+\left\{\begin{array}{ccc}10x-7y=-1\\2x+7y=25\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad12x=24\qquad\text{divide both sides by 12}\\.\qquad x=2\\\\\text{Put it to the second equation}\\2(2)+7y=25\\4+7y=25\qquad\text{subtract 4 from both sides}\\7y=21\qquad\text{divide both sides by 7}\\y=3$
