Answer:
m<ZB is 36 degrees
Step-by-step explanation:
Since they are vertical angles, they are congruent. U set up the equation like this “2x+26=3x+21” and solve for x
subtract 2x from both sides and you’ll get “26=x+21”
subract 21 from both sides and you’ll get “5=x”
now we substitute x for 5!
3(5)+21=
15+21=
36
So m<ZB is 36 degrees!
