Question

The measure of two opposite angles of a parallelogram are (3 x - 4) degree and (60 - X) degree. Find all angles ​

Answer 1

Answer:

Answer

Step-by-step explanation:

angle A=(3x-4)°

B=(60-x)°

Angle A + Angle B =180°

(3x-4)° +(60-x)° = 180°

3x-4+60-x=180°

3x-x=180-60+4

2x=120+4

2x=124

x=124/2

x=62

Angle A = Angle C

Angle B =Angle D

Angle A= (3x-4)=[3(62)-4] =(186-4)= 182

Angle A =Angle C

Therefore Angle C =182°

Angle B=(60-x)=[60-62]=-2°

Angle B =Angle D

Therefore Angle D=-2°
