Question

find the measure of supplementary angle of each of the following angle (1) 132° , (2) 138°​

Answer 1

$\huge\bf\pink{Answer}$

Supplementary angle of 132° be x

Therefore,

$\longrightarrow\bf{132 + x = 180}$

$\longrightarrow\bf{x = 180 - 132}$

$\longrightarrow\bf{x = 48}$

Supplementary angle of 138° be x

Therefore,

$\longrightarrow\bf{138 + x = 180}$

$\longrightarrow\bf{x = 180 - 138}$

$\longrightarrow\bf{x = 42}$

Answer 2

Answer:

(1) 48°

(2) 42°

Step-by-step explanation:

(1) Let the supplement of 132° be x

   132° + x° = 180

   x° = 180° - 132°

   x = 48°

(2) Let the supplement of 138° be y

   138° + y° = 180

   y° = 180° - 138°

   y  = 42°
