Step-by-step explanation:
- 5x+12=6x+7 (opposite sides of a parallelogram are equal)
- 12=x+7 (subtract 5x from both sides)
- x=5 (subtract 7 from both sides)
- Now put x in any of the equations-- 5(5)+12=37 or 6(5) +7=37
Step-by-step explanation:
Supplementary angle adds up yo 180°
So angle 2 is supplementary to angle 3
The actual amount that needs to be divided = 85
The ratio in which the amount needs to be divided = 2:3:5
Let us assume the common ratio to be = x
Then
2x + 3x + 5x = 85
10x = 85
x = 85/10
= 8.5
Then
The ratio in which the number 85 will be divided = 2 * 8.5:3 * 8.5:5 * 8.5
= 17:25.5:42.5
So from the above deduction we can see that the number 85 can be divided in the ratio 17:25.5:42.5
