We know that both of our numbers will need to be negative so that they multiply to get a positive number (the double negatives cancel) but add to get a negative one.
Consider factor pairs of 40.

-40 × -1 = 40 (adds to -41)
-20 × -2 = 40 (adds to -22)
-10 × -4 = 40 (adds to -14)
-5 × 8 = 40 (adds to -13)

Your numbers are -5 and -8.

-5 and -8 both multiply to 40 -5 x -8 = 40 and both add up to -13. -5 + -8 = -13. two negative numbers when added together the answer is still negative. ex: if i owe 2 dollars to someone and 2 to another i owe 4 in total

Which angle determines whether or not quadrilateral SVUT is a trapezoid? What measure would the angle need to be for SVUT to be

Lorico [155]

Answer: The answer is ∠TUV.

Step-by-step explanation: Given in the question a quadrilateral SVUT with ∠SVU = 112°. We need to determine the angle whose measure will decide whether or not the quadrilateral SVUT is a trapezoid.

We know that for a quadrilateral to be a trapezoid, we need only one condition that one pair of opposite sides must be parallel.

So, in quadrilateral SVUT, since the measure of ∠SVU is given, so we can decide it is a trapezoid or not if we know the measure of ∠TUV. As ST and UV cannot be parallel, so its meaningless to determine ∠TSV.

For SV and TU to be parallel to each other, we need

∠SVU + ∠TUV = 180° (sum of interior alternate angles).

Therefore,

∠TUV = 180° - 112° = 68°.

Thus, we need to determine ∠TUV and its measure shoul be 68°.
