Answer: look at the picture
Step-by-step explanation: Hope this help :D
So.. let's say ∡AGB and ∡BGC are say "a" units wide, and ∡CGD and ∡DGE are "b" units wide
notice the picture below
all angles added up together, will make up just a flat line, or 180°
now, notice in the picture, the ∡BGD is really just " a + b " wide, notice the green angle in the picture of ∡BGD, well, we know what a + b is
Line 1 slope is -1
Line 2 slope is 4/5
Answer:
03-a
Step-by-step explanation:
It's an algebraic expression cuz it has an unknown variable (a)
7x8÷4x37x8÷4x3 = 3108/1 = 3108
