Total sum of angles of a triangle is equal to 180 degrees.
First angle = 4x-3 degrees.
Second angle = 6x-6 degrees.
Let the third angle be represented by ![\beta](https://tex.z-dn.net/?f=%5Cbeta)
![4x-3 + 6x-6 +\beta =180](https://tex.z-dn.net/?f=4x-3%20%2B%206x-6%20%2B%5Cbeta%20%3D180)
Add all the terms with x together and all the constants together.
![(4x+6x) + ( -3 -6 ) + \beta = 180](https://tex.z-dn.net/?f=%284x%2B6x%29%20%2B%20%28%20-3%20-6%20%29%20%2B%20%5Cbeta%20%20%3D%20180)
![10x -9 +\beta = 180](https://tex.z-dn.net/?f=10x%20-9%20%2B%5Cbeta%20%3D%20180)
![\beta = 180 - 10x+ 9](https://tex.z-dn.net/?f=%5Cbeta%20%3D%20180%20-%2010x%2B%209)

Answer:
19 times t = how many toy cars Gordon has.
OR
19t= how many toy cars Gordon has
Answer:
Step-by-step explanation:
If in doubt, multiply them out.
(-i)^4 = i^4 = 1 . . . . . results for ±i
(-1)^4 = 1^4 = 1 . . . . . results for ±1
An even power of a negative number is equivalent to the same power of the opposite (positive) number. The even number of minus signs cancel in the final product.

In trig form, unity is 1∠(n·360°) . . . . . for n = any integer
Then the 4th root is ...
1^(1/4) ∠(n·360°/4) = 1 ∠(n·90°) . . . . for n = 0...3 (angles repeat after that)
That is, the roots are ...
- 1∠0° = 1
- 1∠90° = i
- 1∠180° = -1
- 1∠270° = -i
Of these, all but the first are listed among your answer choices. The appropriate selection is <em>all of the above</em>. (recognizing that not all of the appropriate choices are "above" that answer selection).
