Answer:
50 degrees
Step-by-step explanation:
The sum of the interior angles of a triangle is 180. We can find the missing angle of the triangle by subtracting out the two measurement of the triangle that we know from 180.
180 - 31 -19 = 130
This angle would be the alternate exterior angel to the parallel line QP. That angle is supplement to the angle that you are looking for. <QTP would be 50 (180 -130)
Answer:D.6
Step-by-step explanation:
just divide
Answer:
Step-by-step explanation:
x^2 - 6x - 40 = 0.....get the -40 to the other side
x^2 - 6x = 40....now take half of ur x term (6)....so its 3...then square it (3^2 = 9)...now add 9 to both sides
x^2 - 6x + 9 = 40 + 9
(x - 3)(x - 3) = 49
(x - 3)^2 = 49...take sqrt of both sides, eliminating the ^2
x - 3 = sqrt 49
x = 3 (+ - ) 7
x = 3 + 7 = 10 or x = 3 - 7 = -4
so x = 10 or x = -4
This may be true, you would have to compute a few and present argument though. it may have to do with how they factor and may even have deep origins to the Rational roots theorem but I am unsure at the moment.
Answer:
4/7
Step-by-step explanation:
There are 11 odd numbers less than or equal to 21.
There is 1 two.
11 + 1 = 12 ways
12 outcomes/ 21 total outcomes =
4/7
