Step-by-step explanation:
ΔABC has the following angle measures:
∡A: 87° (reason: given)
∡B: 23° (reason: given)
∡C: 70° (reason: sum of all interior angles in a triangle is 180)
Answer:
Step-by-step explanation:
x = 180 - 80 - 55 (Interior angles of a triangle add up to 180 degrees so if we need to find any unknown angle, we'll subtract all the other angles from 180)
x = 45 degrees
