The answer is the number that 'x' must be in order for
that equation to be a true statement. Here's one way
to find out what the number is:
x + 36 = 4x
Subtract 'x' from each side: 36 = 3x
Divide each side by 3 : 12 = x
Answer:
x = 9.
Step-by-step explanation:
42 - 15 = 27
27 ÷ 3 = 9
According to the vertical angle rule we know that x is 40 degrees. The sum of all angles in a triangle make 180, so the sum of x, 60, and the third angle is 180. x is 40 so the third angle is 180-60-40 which is 80 degrees. y is an adjacent angle, which means that the sum of y and 80 degrees is 180. 180-80 is 100, so y is 100 degrees.
If the diameter of the cone is 5, then the radius of it will be half that, or 2.5, thus
