Question

find the angle which is 80 degree more than its supplement​

Answer 1

Answer:

130°

Step-by-step explanation:

Supplement angles = 180°

If one angle is 80° greater than the other, the difference between the 2 angles is 80.

Let $x$ be the angle.

The supplement angle is $x+80$.

We can form the below equation:

$x + (x + 80) = 180$

$2x + 80 = 180$

$2x = 180 - 80$

$2x = 100$

$x = \frac{100}{2}$

$x = 50$

Since x = 50°, the supplementary angle is be 50° + 80° = 130°

The angle which is 80° more than it's supplement is 130°.
