A straight line is 180°. The angles of QRT (2x + 33) and TRS (5x - 21) make up the 180° angle. So you can do:
∠QRT + ∠TRS = 180°
(2x + 33) + (5x - 21) = 180°
2x + 33 + 5x - 21 = 180 Combine like terms
7x + 12 = 180 Subtract 12 on both sides
7x = 168 Divide 7 on both sides
x = 24
Now that you found x, you can find the angles of QRT and TRS.
m∠QRT = 2x + 33
= 2(24) + 33
= 48 + 33
∠QRT = 81°
m∠TRS = 5x - 21
= 5(24) - 21
= 120 - 21
∠TRS = 99°
Answer:
Step-by-step explanation:
To determine the Z - score, it is calculated as follows:
Then:
It means that there are more than 3 standar deviations below the advertised mileage.
Answer:
9 units
Step-by-step explanation:
You can use the distance formula, or you could recognize that since both points have the same x-coordinate, they lie on a vertical line, so the distance between them would be the absolute value of 0 and -9, which is 9.
Hope this helped! :) (Srry I was a little late)
Answer:
-1
Step-by-step explanation:
7+(-1)= 6
6/3 = 2
There are no other solutions I can find to it. It says sum but technically you can add a negative number.
Don´t listen to me if you think that I am wrong. But I hope this helps!!
