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

In a pile of nickels and dimes, the number of nickels is three times the number of dimes and the pike is worth $1.75. How many n
shepuryov [24]
I think there are 7 nickels, because 7 dimes equals 70 cents, plus 7 × 3 = 21 , 21 × 5 = 105
70 + 105 = 175
1.75 = (7 \times 3) \times 5
