HELP NO LINKS PLEASE Challenge: Find the value of x. Then find the measures of the four angles.
Lines G H and N S intersect at point P, forming 4 angles. Angle G P N is labeled (5 plus 8 x) degrees. Angle S P H is labeled (7 x plus 10) degrees.
​(The figure is not to​ scale.)
The value of x is _

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.
