No comprendo. I'm doing a test review and I'm screwed​
MAXImum [283]

Answer:

x = 5

Step-by-step explanation:

sin theta = opposite side / hypotenuse

sin 53 = 4/x

Multiply each side by x

x sin 53 = 4/x *x

x sin 53 = 4

Divide each side by sin 53

x sin 53 / sin 53 = 4 / sin 53

x = 4 /sin 53

x = 5.008542633

To the nearest whole number

x = 5
