Answer: Not enough information
Step-by-step explanation:
We need to know the measure of angle AED, but there is no way to find it, so therefore there is not enough information.
The answer is: " 1024π units² " ; or; " 3215.36 units² " .
______________________________________________________
A = π * r² ;
A = π * 32² = 1024 π units² ;
or, using "3.14" for "π" ;
1024 * π = 1024 * (3.14) = 3215.36 units² .

Multiplying a positive and a negative equals a negative: (+)×(-)=(-)
Calculate the product
Answer: 30°, 67° e 83°.
Step-by-step explanation: The angles are (2x + 16)/5 , x e x + 16°
Adding all the angles, comes:
(2x + 16)/5 + x + x + 16° = 180° ;
2x + 16° + 5x + 5x + 80° = 900° ;
12x = 900° - 16° - 80° ;
12x = 804°° ;
x = 804°/12 ;
x = 67°
So, the first angle is (2,67 + 16)/5 = 30°, the second is 67° and the third is 83°.
Answer:
-1
Step-by-step explanation:
=> -5 + √25 - 4(2)(3) / 4
=> -5 + 1 / 4
=> -4 / 4
=> -1
