Question

an angle is 40 degree more than its supplementary angle find the angle​

Answer 1

Given:

An angle that is 40° more than its supplementary angle.

To find:

The angle that is more than 40° of its supplementary angle.

Solution:

If the sum of two angles add up to 180°, then they are called supplementary angles. Let one of the angles be $x$. Then, the other angle will be $x+40$ according to the given information.

By supplementary angles property,

$x+x+40=180$

$2x+40=180$

$2x=180-40$

$2x=140$

$x=\frac{140}{2}$

$x=70$°

So, the angle is 70° and the other angle is 70+40=110°

The measure of angle is 70°

Answer 2

Answer:

let supp.angle be x

angle =n=+40

Step-by-step explanation:

2n=140

n+n+40=180

2n=180 -40

n=140/2=70.
