Answer:
George Washington
Step-by-step explanation:
The first US president is George Washington
The correct answer to this question is "<span>7 times square root of 74 over 74."</span>
First, we need to get for the "r."
<span><span>r^2 </span>= (−5<span>)^2 </span>+ <span>7^2
r^2 = 25 + 49
r^2 = 74
r = square root of 74
Then, after that, we need to formulate the equation of a sin:
sin x = 7 / r
sin x = 7 / sqrt(74)
sin x = 7 * sqrt (74) / 74</span></span>
