Question

an angle of a parallelogram is 40 degree more than its adjacent angle . find the measure of all angles .

Answer 1

Answer:

70°,70°,110°,110

Step-by-step explanation:

Let the angle be x

So, the other angle = (40°+x)

Sum of all the angles of a parallelogram = 360°

x+x+(40°+x)+(40°+x) = 360°

4x+80° = 360°

x = 360°-80°/4 = 280°/4 = 70°

x = 70°

(40°+x) = 40°+70° = 110°

Hence all the angles of parallelogram are

70°,70°,110°,110°
