Answer:
1) x = 40 B = 10
2) y = 50 U = 60
3) y = 7 x = 13
4) y = 77 k = 13
5) x = 9 A = 35
Explanation:
Couple of things to remember:
1. The sum of all angles in a triangle equal 180
2. The letters in the congruent statements correspond to which angles are congruent to each other.
In the first problem, the statement has C and F in the same position. Both are the last letter of each triangle. Therefore, they are congruent and should be set equal to each other
2x = 80 (Solve by dividing both sides by 2)
x = 40
This strategy can be used to solve the others.
