If a pair of same-side interior angles are congruent, what is the measure of each angle?

Answer 1

Same side interior are also supplementary so the angles must be 90 degrees.

Answer 2

they would have to be 90 degrees each since

a line has 180
same side interior angles are sorta divided by a vertical line
so, lets say one of them was 91, then the other angle would have to be 89 since 180-91=89
the only way is 90

Answer 3

that's grade 12 math? I keep in mind doing this lots till now. yet anyhow one million. attitude 'x' and the different attitude on the line could upload as much as one hundred eighty tiers. in view that one is sixty two tiers, x = one hundred eighty - sixty two, that's 118 tiers. Y is on a line parallel that's intersected by making use of the comparable line that creates the attitude with x. for this reason it could have the comparable fee of x, that's 118 tiers. 2. that's easiest to unravel this as an equation. with the aid of fact the angles of a triangle upload as much as one hundred eighty, all of us be attentive to x + (x+ 20) + (x + 40) = one hundred eighty 3x + 60 = one hundred eighty 3x = a hundred and twenty x = 40 now the attitude interior the triangle beside y is x + 40 = eighty tiers. this implies y=one hundred eighty-eighty = a hundred tiers in view that y is on a in the present day line. 3. you have an equilateral triangle. in view that all factors are of the comparable length, all angles may be the comparable. the three angles of a triangle upload as much as one hundred eighty tiers so each and every attitude could be 60 tiers
