Answer:
21 and 10 :) hope it helps
Step-by-step explanation:
A proper fraction is a fraction less than one, with the numerator less than the denominator so 1/2 is your answer
Given:
A figure.
To find:
The value of x.
Solution:
Draw two parallel lines as shown in the below figure.
If a transversal line intersect two parallel lines, then alternate interior angles are same.
(Alternate interior angle)
(Alternate interior angle) ...(i)
The value of angle d is



Using (i), we get

If a transversal line intersect two parallel lines, then same sides interior angles are supplementary angles.



Now,



Therefore, the value of x is 70.
