Step-by-step explanation:
it's 22 due to the sum all the 2 smallest sides bigger than the biggest
The labeled angle is what's called an inscribed angle. There's a theorem (fittingly called the inscribed angle theorem) that says the measure of this angle is half the measure of the circular arc that it subtends.
In this case, the angle is subtended by an arc measuring 180°. So
(4x + 6)° = 1/2 • 180°
4x + 6 = 90
4x = 84
x = 21
There is nothing in the space. If there were, then the space would not be blank.
Answer:
6
Step-by-step explanation:
The circumference of a circle is 
, so 
. We can use this because the area of a circle is 
. Thus, 
.
