Question

I am stuck on a question I would like some help with

Answer 1

B .80

Explanation:

all interior angles in a triangle=180

180-(70+30)

180-100

=80

Answer 2

m<3 = 80

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
