Answer:
11325.
Step-by-step explanation:
Step 1: address the formula, input parameters & values.
Input parameters & values:
The number series 1, 2, 3, 4, . . . . , 149, 150.
The first term a = 1
The common difference d = 1
Total number of terms n = 150
Step 2: apply the input parameter values in the formula
Sum = n/2 x (a + Tn)
= 150/2 x (1 + 150)
= 22650/2
1 + 2 + 3 + 4 + . . . . + 149 + 150 = 11325
Therefore, 11325 is the sum of positive integers up to 150.
The cosine repeats itself every 360 degrees, and it mirrors at 0 and 180 degrees. It inverts around 90 and 270.
So without using a calculator, you can tell that:
cos(520)=cos(520-360)=cos(160)
cos(160) = cos(180-20) = cos(180+20) = cos(200)
cos(160) is NOT equal to cos(20), it would be -cos(20).
cos(160) = -cos(20) = -cos(-20)
So C is the only one unequal.
