Since a triangle's angles must all together measure 180 degrees, subtract the two angles from 180: 180 - 71 - 63 = 46
He will do both in 12 days since the least common multiple of 3 and 4 is 12. This can be found by making a list of both numbers' multiples. You will see that the first common number or multiple is 12.
Multiples of 3: 3, 6, 9, 12, 15
Multiples of 4: 4, 8, 12, 16, 20

Answer:
B
Step-by-step explanation:
2(420) + 2(245) = x
840 + 490 = x
x = 1330 yards
The correct answer is B.
An undefined slope is indicated by:
x= a number, which looks like a vertical line.
A line perpendicular to that is indicated by:
y = a number, which looks like a horizontal line.
