Find the measurements of each angle.

∆efg and ∆lmn are supplementary angles, m∆efg= (3x + 17)°, and m∆lmn= (1/2x - 5)°

∆efg = ?

∆lmn = ?

m∠EFG =

m∠LMN =

Step-by-step explanation:

Given:

∠EFG and ∠LMN are supplementary angles

m∠EFG =

m∠LMN =

We need to find m∠EFG and m∠LMN

Now we know that sum of the Supplementary angles are 180°

Hence we can say that;

m∠EFG + m∠LMN = 180°

Substituting the given values we get;

Now Substituting the value of x to find the measures of angle;

m∠EFG =

m∠LMN =
