Question

30 × tg(1°) × tg(89°) – 37

Answer 1

30*tg1*tg89-37=30*tg1*tg(90-1)-37=30*tg1*ctg1-37=30*1-37=30-37=-7

Answer 2

To calculate the expression 30 × tan(1°) × tan(89°) - 37, you can use a calculator or perform the calculations manually. However, it's important to note that the value of tan(89°) is extremely large and close to infinity, so this expression will result in a very large positive number.

Here's the calculation:

1. Calculate tan(1°):

   tan(1°) ≈ 0.017455

2. Calculate tan(89°):

   tan(89°) is very close to infinity (approaching ∞).

3. Now, perform the multiplication and subtraction:

   30 × 0.017455 × ∞ - 37

Since we're multiplying by infinity, the result is infinite, and when you subtract 37 from infinity, you still have infinity.

So, the result of the expression is positive infinity (∞).
