Determine the exact value of 𝑥 the following expression given that 0 ≤ 𝑥 ≤ 90.

a) 𝑠𝑖𝑛𝑥 = 3/2

To find the exact value of 𝑥 given that 𝑠𝑖𝑛𝑥 = 3/2, we need to find the angle whose sine is 3/2 within the range 0 ≤ 𝑥 ≤ 90. However, the sine function is only defined between -1 and 1, so there is no real number 𝑥 that satisfies 𝑠𝑖𝑛𝑥 = 3/2 within the given range. Therefore, there is no exact value of 𝑥 for this expression within the given constraints.
