Whats (12-7) x (8-5) - 7 and (16-4) + (10 - 12 divided by 3)
zalisa [80]

Answer:

The answer would be 26

Step-by-step explanation: (Broken down into 2 parts)

-PART ONE- solving (12-7) x (8-5) -7

(12-7) x (8-5) -7 (do whats in parentheses first)

(5)x (3) -7 (multiply 5x3)

15-7 (subtract)

ANSWER- 8

-PART TWO- solving (16-4) + (10 - 12 divided by 3)

(16-4) + (10 - 12 divided by 3) (do what is in parentheses)

12 + 10-4 (add)

22-4 (subtract)

ANSWER- 18

Now combine the two answers 18+8 and you get 26

Therefore, 26 is the final answer.

Hope this helps!!

Find cos ⁡ ( 2 ⋅ ∠ A B C ) cos(2⋅∠ABC)
Pavlova-9 [17]

The value of the cosine function is -0.385

<h3>How to determine the measure of the cosine function?</h3>

The figure that completes the question is added as an attachment

From the figure, we have the following sides

AB = √13

AC  = 3

BC = 2

The triangle is a right triangle.

The angle B is calculated as:

cos(B) = 2/√13

Evaluate

cos(B) = 0.5547

Take the arccos of both sides

B = 56.31

This means that:

cos(ABC) = cos(56.31)

Multiply ABC by 2.

So, we have:

cos(ABC * 2) = cos(56.31 * 2)

Evaluate the product

cos(ABC * 2) = cos(112.62)

Evaluate the cosine

cos(ABC * 2) = -0.385

Hence, the value of the cosine function is -0.385
