Write each trigonometric ratio as a fraction in simplest form. show all supporting work
Nesterboy [21]

Answer: \frac{x}{20}

Step-by-step explanation:

Sine uses the ratio,  \frac{opposite}{hypotenuse} so we can plug in the information we know. since there is no current value for the opposite side of angle A, we can just use a variable to replace it.

sinA=\frac{x}{20}

You can't reduce this any further because there is an unknown variable.

Y - 0.8x = 0.5
Sveta_85 [38]

Answer:

y=\frac{5+8x}{10} , x=x

Step-by-step explanation:

y-0.8x=0.5

y*10-0.8x*10=0.5*10

10y-8x=5

10y-8x+8x=5+8x

10y/10=5/10+8x/10

y=5+8x/10

5*5+8x/10-2.5

8x+5/2-2.5=4x

y=5+8x/10, x=x
