Sagot :
Answer:
angle E =43 degrees
Step-by-step explanation:
since you know the 2 other angles you would add them together, 73+64= 137
a triangle adds up to 180 so you would subtract to get the remaining angle.
180-137= 43.
so your remaining angle (E)= 43.
Answer:
B
Step-by-step explanation:
All three measures of a triangle add up to 180. In triangle ABC, angle A is 64 and angle C is 73 because angle C is congruent to angle F.
Add 64 and 73 together to get 137
Then minus 137 from 180 to get 43.
So now we know that angle B is 43 and since angle B and angle E are congruent, angle E is 43.
