- Ifm^6 INJ= 53 ◦, findm^6 MNL.
For exercises 3-5, determine if the statement is true or false.
- Vertical angles have the same vertex.
- Vertical angles are supplementary.
- Intersecting lines form two pairs of vertical angles.
Solve for the variables.
- Findx.
- Findy.
- If^6 ABCand^6 DBFare vertical angles andm^6 ABC= ( 4 x+ 1 )◦andm^6 DBF= ( 3 x+ 29 )◦, what is the measure
of each angle? - If^6 ABCand^6 DBFare vertical angles andm^6 ABC= ( 5 x+ 2 )◦andm^6 DBF= ( 6 x− 32 )◦, what is the measure
of each angle? - If^6 ABCand^6 DBFare vertical angles andm^6 ABC= (x+ 20 )◦andm^6 DBF= ( 4 x+ 2 )◦, what is the measure
of each angle? - If^6 ABCand^6 DBFare vertical angles andm^6 ABC= ( 2 x+ 10 )◦andm^6 DBF= ( 4 x)◦, what is the measure of
