Question

A/sin(35) = 9/sin(75) = приблизительно 5,3 см Как получилось такое число?

Answer 1

вот это число 24783920

Answer 2

To understand how the value of approximately 5.3 cm was obtained, let's break down the given trigonometric expression and solve it step by step.

The expression provided is: A/sin(35) = 9/sin(75)

Step 1: Determine the value of sin(35 degrees). Step 2: Determine the value of sin(75 degrees). Step 3: Use the given equation to find the value of A.

Step 1: Find the value of sin(35 degrees). To find the value of sin(35 degrees), you can use a calculator or refer to trigonometric tables. The approximate value of sin(35 degrees) is about 0.5736.

Step 2: Find the value of sin(75 degrees). To find the value of sin(75 degrees), again, you can use a calculator or trigonometric tables. The approximate value of sin(75 degrees) is about 0.9659.

Step 3: Use the given equation to find the value of A. Now, plug in the known values into the equation:

A/sin(35) = 9/sin(75)

A/0.5736 = 9/0.9659

To solve for A, cross-multiply:

A * 0.9659 = 9 * 0.5736

A ≈ 5.172 cm

So, the value of A is approximately 5.172 cm.

The given statement that A/sin(35) = 9/sin(75) is incorrect. The correct value of A for the equation would be approximately 5.172 cm, not 5.3 cm.
