Answer:
Step-by-step explanation:
256 = 16×16=4×4×4×4 = 4^4
X^4-4^4 = (x^2)^2 - (4^2)^2
Using algebraic identity a^2-b^2 = (a+b)(a-b)
We get (x^2+4^2)(x^2-4^2)
(x^2+4^2)(x+2)(x-2)
Answer:
X = 53 degrees
Y = 74 degrees
Z = 53 degrees
Step-by-step explanation:
So if you knew that all angles in triangles add up to 180 degrees. You first want to find Y. 180 - 36 - 70 is equal to 74. So, Angle Y is 74 degrees. Line XYZ is a line that has a 180 degree on there. So 180 - 74 and divide that by 2 to find X and Z. 180 - 74 is 106. 106/2 = 53. Therefore, X and Z are 53 degrees, Y is 74 degrees.
Well, first... I am answering for a brainliest, not points :) but here is what I calculated:
The area of the smaller circle is 113.1 cm. The area of the large circle is 615.75 cm.
The answer (or so I hope) is <span>27/50
