Question

16) Find the supplement of the following angles. (a)129 (b)134​

Answer 1

• Supplement angles are those whose sum is equal to 180° .

( a ) 129

Let x be the Supplement of 129 .

so , x + 129 = 180

x = 180 - 129

x = 51 °

( b ) 134

Let y be the supplement of 134

so , y + 134 = 180

y = 180 - 134

y = 46°

hope it helps you..

Answer 2

Given,

Supplementary angle : two angles or arcs whose sum is $180$ degrees.

Take option a,

One angle is $129$, and assume another angle be $x$

From the definition of the supplementary angles,

$129+x=180$

$x=180-129\\x= 51$

Take option b

$134$ is first angle

Assume another angle be $x$

From the definition of the supplementary angles,

$134+x=180\\x=180-134\\x=46$

Therefore, the supplement of the $129$ and $134$ angles are $51$ and $46$.
