Answer:
(8x+13)=(10x-27) being vertically opposite triangles.
Now take the 8 to the next side and minus it by 10x which means 10x-8x, the answer is 2x
Then, do with 27 and 13 also and whatever the answer comes it will be divided by 2, so that is the value of x
x = 20
Step-by-step explanation:
The 2 angles are vertical and congruent, thus
10x - 27 = 8x + 13 ( subtract 8x from both sides )
2x - 27 = 13 ( add 27 to both sides )
2x = 40 ( divide both sides by 2 )
