The answer is A 109
Explanation:
Solve for x when doing 6x+19=7x+4
Then plug in the value of x into 6x+19
Every triangle has a total of 180 degrees so when you plug in the answer for x all angles should add up to 180
70+85+25=180 which means A.30 is the correct answer
(2(30)+10)+(2(30)+25)+(30-5)= 180
