Answer 3

Sure, I can help you with that!

To calculate the value of sin(68°) + sin(52°), you'll first need to find the individual sine values and then add them together.

Step 1: Convert degrees to radians The trigonometric functions in most calculators and programming languages typically work with radians. So, let's convert 68° and 52° to radians.

1 degree = π/180 radians

sin(68°) = sin(68° * π/180 radians) ≈ sin(1.191 rad) sin(52°) = sin(52° * π/180 radians) ≈ sin(0.907 rad)

Step 2: Calculate the sine values You can use a calculator or lookup tables to find the approximate values of sin(1.191) and sin(0.907).

sin(1.191) ≈ 0.9299 sin(0.907) ≈ 0.7926

Step 3: Add the sine values sin(68°) + sin(52°) ≈ 0.9299 + 0.7926 ≈ 1.7225

So, sin(68°) + sin(52°) is approximately 1.7225.
