Answer:
43
Step-by-step explanation:
The angle, 3x + 14 and the other angle 143 are alternate exterior angles. Alternate exterior angles are congruent to each other if the two lines are parallel. So in this case both the angles are considered congruent from the question assuming that they are congruent.
143 = 3x + 14
129 = 3x
x = 43
Answer:
42
Step-by-step explanation:
10x+15x+6x=217
31x=217
217/31=7
6x7=42
It could be 10 which would make the triangle a right triangle, since the values follow the Pythagorean theorem (a^2+b^2=c^2)
