The second angle would be 140⁰. When two angles are supplementary, they add up to 180⁰.
180⁰-40⁰=140⁰
Yes, he is correct, using the distributive property you get the same answer
Assuming that the figure is implying that angles 1 and 2 are the same, we have

So, the measure of angles 1 is

Lines s and t are perpendicular. As you know perpendicular lines, slope is opposite and reciprocal so if slope of line s = 5 then slope of line t = -1/5
