Question

If two angles are supplementary and one angle is 5° more than four times than other, find the angles .

Answer 1

Let one angle be x

2nd angle= 4x+5

Therefore,by the condition

X+ 4x +5= 180(since they are supplementary)

5x+ 5= 180

5x=180-5

= 175

Therefore x= 175÷5

= 35

Therefore 1st angle= x=35degree

2nd angle = 4x+5= 4×35+5=140+5=145 degree

Answer 2

HIII MATE!!!!


When the sum of 2 angles is 180° then it's supplementary angles.


Let the first angle be x

Let the second angle be 5+4x


Now ATQ,


$x + 5 + 4x = 180$



$5x + 5 = 180$


$5x = 180 - 5$


$5x = 175$


$x = 175 \div 5$


$x = 35$


THEREFORE,


1st ANGLE=x=35°


2nd ANGLE=5+4x=5+4×35=145°



THANKS


I THINK IT HELPS....
