Question

Hello I Really need this answered

Answer 1

Answer:

α =  143.13⁰

Step-by-step explanation:

Given;

$Sin \ \alpha = \frac{3}{5} \ \ , \frac{\pi}{2}$

α is determined as follows;

⇒find the arcsine of ³/₅

$\alpha = sin^{-1}(\frac{3}{5} )\\\\\alpha = sin^{-1}(0.6)\\\\\alpha = 36.87 ^0 = 180^0 - 36.87^0 = 143.13^0$

$Thus, \frac{\pi}{2} < 143.13^0$

Therefore, the value of α  that satisfies the given range value is 143.13⁰
