Question

If one angle of parallelogram is 48048^0 less than twice the smallest angle, then the measure of the largest angle of the parallelogram will be:​

A.

104o104^o​​

B.

140o140^o​​

C.

128o128^o​​

D.

120o120^o​​

Correct option is A

Given:

One angle of a parallelogram is 4848^\circ​ less than twice the smallest angle.

Concept used:

In a parallelogram, opposite angles are equal and the sum of the adjacent angles is 180180^\circ

Solution:

The smallest angle of the parallelogram as xx^\circ

​​The other angle is - 2x482x-48^\circ

​​the sum of the smallest angle x and the given angle 2x482x-48^\circ should be 180180^\circ 

x + (2x48)(2x−48^\circ) = 180180^\circ 

348=1803−48^\circ=180^\circ 

3x=2283x = 228^\circ 

x = 7676^\circ 

The measure of the given angle is: 

2x48=2(76)48=15248=1042x−48^\circ=2(76^\circ)−48^\circ=152^\circ−48^\circ=104^\circ 

​The measure of the largest angle of the parallelogram is 104104^\circ 

Thus, correct answer is (a) 104104^\circ​​
