Question

the opposite angles of a parallelogram are 2x+10 degreeand 3x-15 degree find the each angle measurement of parallelogram​

Answer 1

$\large\underline{\pmb{\sf Property...}}$

• $\sf\green{Opposite\:Angles\:of\:parallelogram\:are\:equal}$

$\large\underline{\pmb{\sf Required\:Solution....}}$

• According, to the given identity, the given angles are equal.

$\therefore \sf 2x+10=3x-15$

$:\implies \sf10+15=3x-2x$

$:\implies\boxed{\sf x=25°}$

• As we got the required value of x, let's calculate the angles.
• For that, we just have to put the value of x in the given equation of angles.

$\underline{\rm{\sf 1st \:Angle :- }}$

$:\implies \sf 2x+10$

$:\implies\sf 2(25)+10$

$:\implies 50+10=\red{60°}$

$\underline{\rm{\sf 2nd\:Angle:-}}$

$:\implies \sf 3x-15$

$:\implies \sf 3(25)-15$

$:\implies\sf 75-15 = \red{60°}$

Done :D

ADDITIONAL INFORMATION:-

• Opposite sides of a parallelogram are equal.
• adjacent angles of a parallelogram are supplementary i.e their sum is 180°
• Diagonals of a parallelogram bisect each other
• Each diagonal of a parallelogram separates it into two congruent triangles.

Answer 2

Answer:

1st angle

=2×+10

= 2(25)+10

=50+10=60°

2nd angle

=3×-15

=3(25)-15

75-15=60°
