you can conclude that lines A and B are parallel to each other
Find the average of all the tests on the first and second test. You find the average by adding up all the test scores and dividing it by the number of test scores you added. Then you can see if she did better than the overal average on each of the tests
It is the first answer. Notice that if you multiply it out you get 6x + 30, and they have factored out the 6.
First, we have to figure out the angles on the interior of the triangles. Since the 90° angle and the angle next to it form a straight line, we know that they are supplementary and add up to 180°. We would then subtract 90° from 180° to find the value of that angle, which comes out to be 90°. Next, since the angle measuring 125° and the angle next to it are supplementary, we would repeat the same procedure: 180° - 125° = 55°. Now that we know the values of two of the interior angles of the triangle, we can solve for the third. The angles of a triangle should add up to 180°, so we can solve for <em>p</em> like this:
90 + 55 + <em>p</em> = 180
145 + <em>p</em> = 180
<em>p </em>= 180 - 145
<em>p</em> = 35
The value of <em>p</em> <em />is 35°.
