Answer:

x=5, y=7

Step-by-step explanation:

We have x=5 already given to us, so now plug it into x+y=12.

5+y=12, subtract 5 to the right. y=12-5, to get y=7

If the measure of an exterior angle drawn at vertex M

Rom4ik [11]

Answer:

Step-by-step explanation:

We are given that measure of an exterior angle which are drawn at vertex M=x

We have to find the value of measurement of angle L+measurement of angle N.

Exterior angle:It is defined as that angle of triangle which is formed by the one side of triangle and the extension of an adjacent side of triangle. The measure of exterior angle is equal to sum of measures of two non-adjacent interior angles of a triangle.

Angle L and angle N are two non-adjacent angles of a given triangle LMN.

By definition of exterior angle

x=Measure of angle L+Measure of angle N
