Answer: The largest angle is 7x
Step-by-step explanation:
Their sum is 180, so
3x + 5x + 7x = 180
5x = 180 --> x = 12
The largest angle is 7x, which is 7(12) = 84
The answer would be 680 because 20% of 850 is 170 so 850-170=680.
2x + 2 = 3x - 52
-2x -2x
2 = x - 52
+52 +52
54 = x
24/100 and 6/25 is are some of the equivalent form
