Mathematics

Answer:

r=-6

Step-by-step explanation:

First, we need to subtract 6 from each side, so that we can begin to isolate r.

18=6-2r\\\\12=-2r

Next, we can divide each side by -2

12=-2r\\\\\frac{12}{-2} =\frac{-2r}{-2} \\\\-6=r

-6 is the answer. Subtract 6 from both sides. 12=-2r, divide by -2 on each side. -6= R

How many degrees is angle “X”?
aleksley [76]

Answer:

The answr is 102 degrees. Here's why

Step-by-step explanation:

The square means the angle is 90 degrees. Therefore, for the big triangle, we already know 2 of the degrees, 50 and 90. A triangle's degrees add up to 180. 50+90=140. 180-140=40. This means the top angle is 40. Now finding X is easy, because we already know the other 2 points in the triangle, which are 38 and 40. Add those up, you get 78. 180-78=102, your answer. The triangle is 102 degrees.
