One way is to first find the measure of one external angle:-
Measure 1 ext angle = 360 / 10 = 36 degrees (Note the sum of the external angles of all polygons is 360 degrees)
So the internal angle = 180 - 36 = 144
So sum of the internal angles
= 10 * 144
= 1440 degrees (answer)
Answer: x2 + 2xy + 2xz + 2y + 2z
Step-by-step explanation:
x2+2x(y+z)+(y+z)2
Final result :
x2 + 2xy + 2xz + 2y + 2z
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2".
Step by step solution :
Step 1 :
Equation at the end of step 1 :
((x2)+(2x•(y+z)))+2•(y+z)
Step 2 :
Equation at the end of step 2 :
((x2)+2x•(y+z))+2•(y+z)
Step 3 :
Final result :
x2 + 2xy + 2xz + 2y + 2z
Answer:
Step-by-step explanation:
Hello, please consider the following.
We take y different from -5, as dividing by 0 is not allowed and we can compute as below.
Thank you
Answer is #3. -30
Reason
1 and 2 are absolute values so they are 30, the 4th answer is plus or minus, the question says “below sea level” which is a negative number so it is -30.
Answer:
21.325 is the correct answer
