A line is 180°, so the supplementary angel makes up the difference between. 180 - 60 = 120°
ANSWER

EXPLANATION
The given fractions are:

We factor to obtain:

We cancel the common factors to get:

We multiply the numerators and also multiply the denominators to get:

Therefore the two fractions simplifies to 
Shortest side (a) = 58
middle side (b) = 64
longest side (c) = 77
the 3 sides a + b + c = 199
b = a + 6
c = a + 19
substitute your new values for b & c into your original formula, so:
a + (a+6) + (a+19) = 199
3a + 25 = 199
3a = 174
a = 58
then substitute 58 into your b & c formulas to figure out the rest
b = a + 6 = 58 + 6 = 64
c = a + 19 = 58 + 19 = 77
Answer:
a) (x+2)(x+3)
b) (x+2)(x+3)=0, x=-2 and x=-3
Step-by-step explanation:
3.875 Should be adding to 6.125 to get 10, however if you want an easier way of checking this. Do 3.875 + 6.125 and you'll get exactly 10. Click thanks <3
