The value of a is D)73 I think because 180-107 since a straight line is 180 u just subtract the angle from it. hope this helps.
Answer:
The answer to your question is : 33.3 (Rounded).
Step-by-step explanation:
I got this answer by dividing 19.6 by 20, which gave me 0.98.
Then, I multiplied 0.98 by 34, which gave me 33.32.
After rounding, 33.3 is your answer.
Hope this helped!!
x=3
multiply 2 to both sides to cancel denominator
subtract 8x from both sides and then divide by 2
