Answer:
m∠CAB = 40°
Step-by-step explanation:
DAC = 99
DAB = 59
B is inside DAC, and so is DAB. So CAB must add to 59 to get to 99, nothing over that because it's inside DAC.
So 99 - 59 = 40
CAB must be 40°
That's all I can say for now. Hope this helps and a thank won't hurt! :)
Answer:
n = 5, n = -7/2
Step-by-step explanation:
2n + 5 = l
n - 4 = w
A = l × w = 15
(2n + 5)(n-4) = 15
2n^2 - 8n + 5n - 20 = 15
2n^2 -3n - 35 = 0
(2n + 7)(n - 5) = 0
2n + 7 = 0 or n - 5 = 0
n = -7/2 or n = 5
Since the diameter of the circle is 6 inches, then the radius will be half that, or 3 inches,
three and twenty-seven thousand, five hundred twenty-five hundred-thousandths
