Solve for x (to 2 decimal places)
1. Cos70=x/15
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.
