Question

if the supplement angle of an angel is 4 degree more than its thrice, then the measure of the angle is

Answer 1

Hi,


➡️Solution:

As we know,if two angles are Supplementary,then sum of both is equal to 180°.

ATQ

supplement angle of an angel is 4 degree more than its thrice, then the measure of the angle is ??

➡️let us take one angle as x°,then other will be 180-x°

So,

180-x°= 3x°+4

180-4 = 3x°+x°

4x° = 176

x° = 44°

So, One angle is 44°,other will be 180-44 = 136°.


Hope it helps you.

Answer 2

we know, supplement angle means sum of two angle should be 180° . if A is x° and then B should be (180- x)° for supplement angle .

Let first angle is x°
then, other angle should be (180 - x)°
according to question,
the supplement angle of an angle is 4° more than its thrice.
so, (180 - x)° = 3x° + 4°

=> 180° - x° = 3x° + 4°

=> 176° = 4x°

=> 44° = x so, other angle = (180 - 44) = 136°

hence, angle is 136° and 44° .
