m<MBT= 28°
Step-by-step explanation:
because it is an angle bisector, <MBN is equal to <MBT. meaning the angle splits the in half.
so you would set the equation up as such:
17x-6=5x+18
add 6 to 18 which gives you 24
17x=5x+24
subtract 5x from 17x which gives you 12x
12x=24
divide 12 from each side which gives you 2
x=2
now plug in 2 for x in the equation for <MBT which gives you 5(2)+18
5(2)= 10 which gives you 10+18
leaving you with 28.
hope this helps!❤
