I think you would most likely add all of them well I think
Answer:
<B = 15
Step-by-step explanation:
A triangle adds up to 180 degrees.
Since these triangles are similar, the sides are located in the same spot. (A is in same spot as D, etc.)
A=75
F=90
75 + 90 + x = 180
165 + x = 180
x = 15
You go up 4 times and go to the left 2 times so the slope would be 4/-2
NO they are not proportional
3/7 = .4285714
6/9 = .66666
x^8/x^5=27
x=3 when you flip the equation (rounded number)
