Answer:
m<3 = 80
Step-by-step explanation:
We know that the sum of all the angles in a triangle is 180.
Thus, we can find the m<3 using the equation 180 - (70 + 30) = m<3
Simplifying gives us m<3 = 80
Answer:
B .80
Step-by-step explanation:
all interior angles in a triangle=180
180-(70+30)
180-100
=80
