Answer:
Hello! answer: 40
We know 1 angle is 50 degrees so that means the angle across will also be 50 degrees so that means 2 will be 40 degrees cause that is a complimentary angle and complimentary angles add up to 90 Hope this explains well!
Answer:
csc(x)
Step-by-step explanation:
cos(x)cot(x)+sin(x)
We know that cot(x) = cos(x)/ sin (x)
cos(x)cos(x)/ sin(x)+sin(x)
cos^2 (x)/ sin + sin (x)
Getting a common denominator
cos^2 (x)/ sin + sin (x)* sin (x)/ sin(x)
(cos^2(x) + sin^2(x)) /sin(x)
We know that (cos^2(x) + sin^2(x)) = 1
1/sin (x)
1/ sin (x) =csc(x)
csc(x)
Answer:
Option A.
Step-by-step explanation:
Definition of Boyle's law: a law stating that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature. There is thus a relationship between volume and pressure of the gas thus option B and C are incorrect.
Step-by-step explanation:
The question above is answered below.
Consecutive numbers are set of numbers that follow one another in ascending or descending order, e.g. 1, 2, 3, 4, 5....
The sum of three consecutive numbers = 72
Let the unknown consecutive numbers be represented by x+1, x+2 and x+3 such that:

Remove the brackets

Collect like terms and simplify


Make 3x subject of formula by subtracting 6 from both sides


To obtain the value of x, divide through by the coefficient of x, which is 3. Hence;


Since x = 22,



The smallest of these numbers is 23.
Check,
23 + 24 + 25 = 72
