Answer: m<1 is 60, m<2 is 60, and m<3 is 120
Step-by-step explanation:
M<1 is 60 and m<2 is also 60 because the interior triangle angles have to equal 180 so M<1 + m<2 + 60 = 180 so m<1 and m<2 are both sixty.
m<3 is 120 because m<2 and m<3 are supplementary so if a supplementary angle is equal to 180 then m<2 + m<3 = 180 and m<2 is 60 so m<3 is 120.
In order to solve this exercise you need to remember the following symbols in Inequalities:
1. The meaning of this symbol is "Greater than":

2. The meaning of this one is "Less than":

3. The following symbol means "Less than or equal to":

4. And this one means "Greater than or equal to":

Knowing the above, you can determine that the statement "c is less than 6", can be written as the following inequality:

The answer is:
