Answer:
x =27
Step-by-step explanation:
from Z angls rule the agle (BDE) =72
and total angl on D =180
so, 2x +2x+72=180
4x = 180 -72
4x = 108 (divied both sides by 4)
x= 27
Answer: If the product of any two numbers in the list is equal to 0, you can't conclude that the list is composed only by zeroes. In fact, suppose that you have a list of N numbers which are all zeroes except one. Whenever you multiply two elements of this list, you either multiplies two zeroes, or you multiply the non-zero element by a zero element, and so the result is zero, but the list is not composed by zeroes only.

Step-by-step explanation:
To find this you multiply the 2 numbers together. 3*3/4=2.25.
2.25 in fraction form is
Answer:
radius = 65 cm
Step-by-step explanation:
(See image attached for better comprehension)
To find the value of the radius, we just need to draw a triangle, where one side is half of the chord (the distance from the chord to the center creates a point that divides the chord in two equal segments), other side is the distance from the chord to the center, and the hypotenusa will be the radius.
So, using Pythagoras' theorem, we have that:
r^2 = 56^2 + 33^2
r^2 = 4225
r = 65 cm
