Which expression can be used to find the length of AT?
1 answer:
The length of AT = cos 66°*12.5. option B is the correct answer
The trigonometric ratio cosine is used to connect the angle between the neighboring leg and the hypotenuse of a right triangle.
From the question, we have,
cos 66° = AT/12.5
AT = cos 66°*12.5
The length of AT = cos 66°*12.5
Divide:
Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups. When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers. One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things. It is a mathematical operation used for equal distribution and equal grouping.
