Answer: 60
Step-by-step explanation: The angle of one side of a straight line is 180. We have one angle (120) from the bottom of the line. 180-120=60
Answer:
total = 0;
for (k = 0; k <= n; k++)
total += Math.pow(k,3);
Step-by-step explanation:
Here the variable total is declared and initialized with a value zero
Then a for loop is defined with a counter k whose initial value is set to zero then a condition for the loop is that the counter k does not exceed n k<=n and then within the loop a statement which add the cube of the counter k to the variable total and still assigns it to the variable total is defined
total += Math.pow(k,3);
What this program does is to obtain the sum of the cubes of k
Which place value are trying to round the number?
Answer:
C
Step-by-step explanation:
∠ AFD = ∠ AFB + ∠ BFC + ∠ CFD
The 3 angles form a straight angle and sum to 180°, that is
4x + 5 + 6x + 3 + 5x + 7 = 180, that is
15x + 15 = 180 ( subtract 15 from both sides )
15x = 165 ( divide both sides by 15 )
x = 11
∠ CFD = 5x + 7 = 5(11) + 7 = 55 + 7 = 62°, thus
∠ AFE = ∠ CFD = 62° ( vertical angles are congruent )
