Answer:
4.1
Step-by-step explanation:
I converted the numbers to decimals: 3.4 and 7.5. 3.4+a=7.5. 7.5-3.4= 4.1
The answer is (A) 15.
(6x -10) makes 80 and (6x+10) makes 100
together that equales 180 degrees. since it is a straight line the sum of the the two would have to equal 180. hope this helped :D
