Question

please solve this maths problem​

Answer 1

Given:

in a parallelogram,

angle A=(2x+25)°

angle B=(3x+5)°

Solution:

OPPOSITE ANGLES ARE EQUAL IN A PARALLELOGRAM,

So,

angle A=angle C

angle B=angle D

BY ANGLE SUM PROPERTY,

Sum of all angles in a parallelogram=360°

angle A+angle B +angle C+angle D=360°

(2x+25)°+(3x+5)°+(2x+25)°+(3x+5)°=360°

10x+60°=360°

10x=360°-60

10x=300°

x=30°

So, angle A=angle C=85°

angle B=angle D=95°
