First figure out what 851 minutes 473 equals to, which is 378
So both sides of the equation should equal to 378
Plus 470 and 378 together
Which equals to 848
So the answer is eight hundred and forty eight
Answer:
Step-by-step explanation:
The sum of the angles is ...
x° + (x +8)° + 2x° = 180°
4x +8 = 180 . . . . . . . . . . . collect terms, divide by °
x +2 = 45 . . . . . . . . . . divide by 4
x = 43 . . . . . . . . . . subtract 2
x +8 = 51
2x = 86
The angles are 43°, 51°, 86°.
