Complete the two-column proof.

given: < 2 = < 4, m< 2 = 110
proof: m< 3 = 70

< 2 = < 4, m< 2 = 110 given
m< 2 = m< 4 definition of congruent angles
m< 4 = 110
< 3 and < 4 are a linear pair definition of a linear pair(shown in diagram)
< 3 and < 4 are supplementary linear pair postulate
m< 3 + m< 4 = 180
m< 3 = 70

5x = -15

5 represents time in weeks

x represents the quantity I am trying to find

-15 is my result after a 5 week period of temperature decline at a rate of x.

Now when we solve for x, we get x = -3.

Therefore the rate of which the temperature has dropped has been identified at -3 degrees per week of temperature decline.

Can you let me know if this helps, thx
