Problema Solution

mo bisects angle lmn angle lmo is (13x-31) angle nmo is (x+53) solve for x and then find angle lmn

Answer provided by our tutors

Themajor angle is lmn, which is bisected into lmo (13x-31) and nmo (x+53)... so the two bisected angles are equal and the major angle is the sum of the two minor angles. 

(13x-31)=(x+53)

x=7

The angle for lmn is the sum of lmo plus nmo:
(13(7)-31)+(7+53)

120

The major angle, lmn, is 120 degrees.
