Answer:
d - 3/2
Hi again! Like in my previous answer, difference implies subtraction, therefore, we know that this expression must be a subtraction between two terms. The first term is d, and the second term is 3/2. A fraction is equivalent to stating a division expression.
Step-by-step explanation:
Remember that the angles of a triangle is 180 so:
(7x+8) + (5x+2) + (7x-1) = 180
7x+8+5x+2+7x-1=180
7x+5x+7x=180-8-2+1
19x=171
X= 171/19
X=9
Therefore x=9
