Question

in a parellelogram abcd find the measure of all the angles if one angle measures 68°
​

Answer 1

Answer:

a=112

c= 112

d=68

d=68

hope this helps

Answer 2

Answer:

Step-by-step explanation:

Let ∠b = 68°

∴∠d = ∠b =68° ( in a parallelogram , opposite angles are equal )

let the measurement of ∠a =  x°

∴∠c = ∠a = x° (∵opposite angles )

so, 68° + x° + 68° + x° = 360° [ ∵ sum of all angles in a parallelogram is 360°)

⇒2x° + 136° = 360°

⇒2x = 360° - 136°

⇒x° = 224/ 2 = 112°

hence the measure of all the angles are 68° , 112° , 68° and 112°
