To solve all of these, you put the expressions you've been given into an equation that equals whatever number the sheet tells you is the sum of the angle measures. Then you just substitute it in to find the angle measures. I'll do the first one for you but tell me if you want me to do the rest:
2k + k + 45 = 180
3k + 45 = 180
- 45
3k = 135
÷ 3
k = 45°
45 × 2 (2k) = 90
Again let me know if you want the answers and working to the other two :)

Answer:
yes it is very slopey..and.. steep
Answer:
x=9 y=-4
Step-by-step explanation:
1) to eliminate a variable make sure they are the same so you can cancel them out
lets eliminate x
-3 and -2 share a GCF of 6 so
2(-3x-4y=-11)
-6x-8y=-22
3(-2x-6y=6)
-6x-18y=18
-6x-8y=-22
-
-6x-18y=18
--------------------------
10y=-40
y=-4
2)substitute y as -4 in the second equation
-2x-6(-4)=6
-2x+24=6
-2x=-18
x=9
Answer:
5x^7 + 4x^4 - 2x^2 + 5x - 19
Step-by-step explanation:
Start by copying 5x -10 +3x^4 - 2x^2 here. Next, add x^4 to +3x^4, -9 to -10, and 5x^7:
5x - 10 +3x^4 - 2x^2
- 9 +x^4 + 5x^7
-----------------------------------------
5x - 19 + 4x^4 - 2x^2 + 5x^7
Now rearrange these terms in descending order by powers of x:
5x^7 + 4x^4 - 2x^2 + 5x - 19 (answer)
