Answer:
Step-by-step explanation:
To Find: <NMX
<CBX & X
1) <NMX = <MNO + <NOM
: <NMX = 87' + 43'
: <NMX = 130'
2) <CBX = <BAC + <ACB
:<CBX = 70' + 45"
:2x + 15' = 115'
:2x = 100
:x =50
: <CBX = 115'

It's degree not this [ ' ] ok?
Here is my explenation:
To Find: <NMX
<CBX & X
Solution: We know, exterior angle is equal to sum of opposite in interior angles.
1) <NMX = <MNO + <NOM
: <NMX = 87' + 43'
: <NMX = 130'
2) <CBX = <BAC + <ACB
:<CBX = 70' + 45"
:2x + 15' = 115'
:2x = 100
:x =50
: <CBX = 115'
