Question

two adjecent angles of parallelogram are( 2x +30)° and (3x-30)° .what is the value of x ?​

Answer 1

Answer:

(2x+30°)+(3x-30°)=180°

(reason - the sum of adjacent sides of a parallelogram is 180°)

= 2x+3x+30-30= 180°

= 5x= 180°

=x= 180÷5

=x= 36°

‎ ‎

Angles are -

$\rightarrow$2x+30= 72°+30= 102°

$\rightarrow$3x-30= 108°-30= 78°

Answer 2

Answer:

we know that the sum of two adjacent angle of parallelogram is always equal to 180°

then,

(2x +30)° + (3x-30)°=180°

2x+3x + 30°-30°=180°

5x+0=180°

5x=180°

x=180/5

x=36°

the value of x is 36°....
