Answer:
108
Step-by-step explanation:
Since angle AFB and angle BFC are next to each other and form a straight line, we can subtract 72 from 180 to get the missing angle measurement. (all straight lines add up to 180)
180-72=108
So 108 would be your answer
(6x-12)/10 factor out 2
2(3x-6)/(2(5))
(3x-6)/5 and you can factor out 3 from the numerator too
3(x-2)/5 which can be expressed as:
0.6(x-2)
Step-by-step explanation:
Pythagoras theorem:
80^2+39^2 =x^2
square root of 7921 = square root of x^2
x=89
