Answer:
Using the calculator angle whose cos is 0.9511 is 18 degrees
Sine of the complementary angle = 0.9511 also
Step-by-step explanation:
The sine of the complementary angle( which is 90-18 = 72 degrees) is same value 0.9511
Answer:
<em>Leila would make a profit of $48</em>
Step-by-step explanation:
~ Knowing that there is some sort of proportion that can be formed through Leila and Jo's profit, we could form even a proportionality to compute the profit Leila makes given jo's profit of $60 ~
<em>If is is known that Leila: Jo, 4: 5, we could form such a proportion:</em>
4 5 ⇒ where x - Leila's profit knowing Jo's profit of $60
x 60
<em>Now let us solve for x, through cross multiplication:</em>
5x = 60 * 4,
5x = 240,
x =<em> profit of $48</em>
