Interior angles of triangles equal 180.
So angleTUV = 24 degrees
A straight line will equal 180 degrees. If angle U is 24 degrees in the interior angle, the exterior is 156 degrees.
Angle VUX is 156 degrees
X=10
Explaination:
130=8x+50
-50 -50
80=8x, then divide each side by 8 to get the variable alone
In your function the possible value of X by means of simplifying it is 1.56 so the table would be a straight horizontal line in the plane. I hope you understand my answer and if you have more clarification, feel free to ask for more, have a good day
6.7-2.3= 4.4 is the answer to the problem
