Answer:
19) 28°
20) 60°
21) 17°
Step-by-step explanation:
19)
Supplementary angles:
(x + 12)º + 140º = 180º
x + 12 + 140 = 180
x = 180 - 140 - 12
x = 28º
20)
Angles at a point:
(- 24 + x)° + 24° + 300° = 360°
- 24 + x + 24 + 300 = 360
x = 360 - 300
x = 60°
21)
Vertically opposite angles:
(1 + 3x)° = 52°
1 + 3x = 52
3x = 52 - 1
3x = 51
x = 17°
I think K=1.123
you have to find by how much it's increasing, think of 6(1/2) times WHAT equals 7(1/3)
6(1/2)a=7(1/3)
a=1.123
That means each side will be the same times 1.123
x=4.492
you can round that to 4.49 or 4.5 or 5
Answer: 8y^6x^6
Step-by-step explanation:
Volume = l*w*h so multiply all the variable by <u>multiplying the numbers and adding the exponents</u> so
2y^2*4x^4y=8y^3x^4
then 8y^3x^4*x^2y^3=8y^6x^6
108 minutes because 50 percent of 240 is 120 so take 5 percent away and it is 108
17m
Because horizontal distance is 8m, vertical distance is 15m
So distance between A and Enid square root of 8^2+15^2
