Solve for x (to 2 decimal places)

Question

1. Cos70=x/15

Answer 1

To solve for x, we can use the cosine function to find the value of x.

Given: cos(70) = x/15

First, let's find the cosine of 70 degrees using a calculator or trigonometric table:

cos(70) ≈ 0.342

Now, let's substitute this value back into the equation:

0.342 = x/15

To solve for x, we can cross-multiply:

x = 0.342 * 15

x ≈ 5.13

Therefore, x is approximately 5.13 to 2 decimal places.
