Answer:
68.5
Step-by-step explanation:
Angles DEC and DAC are right angles, so their sum is 180°. DECA is a quadrilateral, which has a sum of interior angles equal to 360°. Then angle ACE is the supplement of angle D:
∠ACE = 180° -43° = 137°
Inscribed angle ABE has half the measure of central angle ACE, so we have ...
x° = 137°/2
x = 68.5
There is only 1
(x + 3)^3 + 10 = 0
(x + 3)^3 = - 10
(x + 3) = cuberoot(-10)
x = -3 + cuberoot(-10)
The elements you can see in the reaction are Calcium(Ca), Hydrogen(H), and Oxygen(O). So there are 3 elements in the chemical reaction.
The 3 is a positive integer and the 7 is a negative integer so you would do "KFC" also known as (Keep, Flip, and Change)
3
("Keep" the 3 positive)
-
("Flip"the minus sign into a plus sign)
-7
("Change" the negative sign into a positive sign)
So therefore, you would have:
3 + 7, which equals 10
Answer:
3
Step-by-step explanation:
9 divide by 3 is 3 itself so the answer is 3
