Answer:
x = 11 ,
<APT = 6x + 1 ➡ 67°
<PTA = 9x - 24 ➡75°
<PAT = 5x - 17 ➡ 38°
Step-by-step explanation:
(5x - 17) + (9x - 24) + (6x + 1)=180°
20x - 40 = 180°
20x = 180° + 40°
20x = 220°
x = 11

hope this helps
this is because the .3 is repeating but it is the same number repeating(it is a pattern)
Answer: 2
There are 10 triangles, that represent the number 2. There are 8 circles, that represents the number 1. To make this 1:1, we must add 2 circles.
10:10 = 1:1
The answer to the question is 2 circles.
Hope this helps you!
Answer:
-276
Step-by-step explanation:
We'll use the method of cofactors. Use the coefficient +6 for
9 2
8 10
This gives you one third of the solution: 6 {(9)·(10) - (8)(2) }, or 444.
Next, use the coefficient 9, taking care to change the sign to -9 as follows:
9 1
-9 | | = -9(90 - 8) = -9(82) = -738
8 10
Finally with +2 as y our coefficient, evaluate the cofactor
9 1
9 2
ending up with
+2(18-9) = +2(9) = 18
Finally add these three results together:
+444 - 738 + 18 = -276
This, the determinant, D, is -276 (the fourth answer choice)
It 730 because when you round to the nearest ten its 740
So 10 more will make it 740
