Answer:
AC 4x + 16
Angle BEC is 72 degrees
Step-by-step explanation:
AE is 2x + 8, and AC is 2 times bigger, so 4x + 16
Angle EAD is the same as angle EDA, which is 54 degrees, a triangle has 3 sides measuring 180 degrees total, 54 + 54 = 108, so the last angle is 180 - 108 = 72, angle AED is 72, since angle BEC is the same as angle AED, it is also 72 degrees
Answer:
8π
Step-by-step explanation:
The equation for the area of a circle is π multiplied by the diameter so it's just 18π-10π.

namely, let's rationalize the denominator in the fraction, for which case we'll be using the <u>conjugate</u> of that denominator, so we'll multiply top and bottom by its <u>conjugate</u>.
so the denominator is 5 + i, simply enough, its conjugate is just 5 - i, recall that same/same = 1, thus (5-i)/(5-i) = 1, and any expression multiplied by 1 is just itself, so we're not really changing the fraction per se.
Tasha is correct. The distributive property applies, so she can use any factor she likes, even an irrational one.
120 - 36 = 12*10 - 12*3 = 12(10 - 3) . . . . . using the GCF (=12)
_____
This can also be written
... 120 - 36 = π((120/π) - (36/π)) . . . . . . . . using an arbitrary irrational factor
