so, 25 whole watches and hmmmm just the wristband of another maybe.
As with any triangle, the sum of angles is 180°.
(a)
(x -5) +(3x +30) +35 = 180 . . . . . sum of angles is 180
4x +60 = 180 . . . . . . . . . . . . . . . . collect terms
4x = 120 . . . . . . . . . . . . . . . . . . . . subtract 60
x = 30 . . . . . . . . . . . . . . . . . . . . . . divide by 4
(b)
Angle A = x -5 = 30 -5 = 25
Angle B = 3x +30 = 3*30 +30 = 120
the answer is 5 dimes and 1 nickel.
hope this helps <3
What problem I cannot see The question
Yes it is. log(1) and ln(1) both equal zero. But you cannot take the logarithm of 0.
