Answer: 100 degrees

Step-by-step explanation:

So the blue 100 degrees and x are vertical angles, which mean they are equivalent to each others. This mean that x = 100 degrees :)

Hope this helps :)

The opposite angles where two lines cross are called <em>vertical angles.</em><em> </em>

Say it with me: "Vertical angles are congruent!"

Find x, if 3x − 5(y + x ) ^2 = 16 and 4x + 2(y + x )^ 2 = 30
lana66690 [7]

Answer:

x = 7

Step-by-step explanation:

Start by solving for (y+x)^2 which is a common expression for both equations. Then in the first equation:

3\,x5\,(y+x)^2=16\\3x-16=5\,(y+x)^2\\(y+x)^2=\frac{3\,x-16}{5}

and in the second equation:

4\,x+2\,(y+x)^2=30\\2\,(y+x)^2=30-4\,x\\(y+x)^2=15-2\,x

Now we make the two (y+x)^2 expressions equal so we get:

\frac{3\,x-16}{5} =15-2\,x\\3\,x-16=75-10\,x\\13\,x=75+16\\13\,x=91\\x=7
