step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

First, you would do the math.
52 + 23 + 10 + 78 = 163

Now, using the process of elimination and common sense, we can narrow down the answer to A. All you have to do is check it.
78 + 10 + 23 + 52 = 163

So, 78 + 10 + 23 + 52 = 52 + 23 + 10 + 78

Your answer would be A. 78 + 10 + 23 + 52

A simple method of checking the sum of arithmetic problems is by using the "digit sum" method. The digit sum can be obtained by adding the digits of a number together, until you get a single-digit number. In case you get a double-digit number, just add them again until you get a single digit number.

Let's try it with an example.

Given the numbers 143, 876, and 534, their digit sums would be:
144 : 1 + 4 + 3 = 9 (same as 0)
876 : 8 + 7 + 6 = 21; 2 + 1 = 3
534 : 5 + 3 + 4 = 12; 1 + 2 = 3

Getting the digit sum is actually getting the number modulo 9, which in other words, is the remainder of that number divided by 9. Since you now have an understanding of the digit sum, how can it be used to check the sum of the problem above?

By comparing the sum of the digit sums of the addends and the digit sum of the obtained sum, you can determine if the arithmetic process was done correctly. Let us do this below:

104 + 34 + 228 + 877 = 1243

Using the digit sum method:

104 : 1 + 0 +4 = 5
34 : 3 + 4 = 7
228 : 2 + 2 + 8 = 12; 1 + 2 = 3
877 : 8 + 7 + 7 = 22; 2 + 2 = 4

5 + 7 + 3 + 4 = 19; 1 + 0 = 1

Comparing with the digit sum of the sum (1243):

1 + 2 + 4 + 3 = 10; 1 + 0 = 1 (OK)

As we can see, the digit sums are the same, so we can say that the arithmetic process has been done correctly.

The answer would be D. 78 + 10 + 23 + 52.

Step-by-step explanation:

For number 3 it is D

08.10.2020 07:56

by adding the numbers in a different order would be a way to check so the answer is:

C. 877 + 228 + 34 + 104

08.10.2020 07:56

By adding 104+34 and then 228+877, Then adding both of the results and finally subtracting the answer by one of the factors.

Explanation:

Which will be...

104+34=138

228+877=1,105

138+1,105=1,243

1,243-1,105

Which will result as 138. Which is also one of the factors you added earlier, that's basically what your looking fro when checking and subtraction and/or addition problem.

A. 78 + 10 + 23 + 52

Step-by-step explanation:

We can solve the problem by using the commutative property: "in an addition, changing the order of the operands does not change the result.

The original addition is 52 + 23 + 10 + 78. We see that option A is exactly the same addition, only the order of the numbers has been changed:

78 + 10 + 23 + 52

Therefore, the two additions are equivalent.

08.10.2020 07:56
52+23=75
10+78=88
88+75=163
that's one way
03.08.2020 23:07
Well first off those numbers add up to 163.

A way to check this is to add 52 with 23 which is 75 then add 78 by 10 which is 88 now add 75 with 88 which is 163
