What is the measure of angle l in parallelogram lmno? 20° 30° 40° 50°

Sagot :

The measure of the angle L in the parallelogram LMNO with the given conditions is equal to 40°.

As given in the question,

In the parallelogram LMNO,

Measure of angle L = (2x)°

Measure of angle O = (4x +60)°

In parallelogram LMNO,

LM is parallel to NO

And LO is the transversal

∠MLO and ∠NOL forms the interior angles

Interiors angles formed by two parallel lines are always supplementary.

m∠L + m∠O = 180°

⇒ (2x)° + (4x + 60)° = 180°

⇒ 6x° = 180° - 60°

⇒ x° = 120°/6

⇒ x° = 20°

Here, m∠L = 2x°

                  = 2(20°)

                  =40°

Therefore, the measure of angle L in the parallelogram is equal to 40°.

The complete question is :

What is the measure of angle L in parallelogram LMNO such that measure of angle L is (2x)° and measure of angle O is (4x + 60)° ?

a. 20°               b. 30°                c.  40°                   d. 50°
