4 0

Answer:

BC = 20.7

Explanation:

  • Formula used: a² = b² + c² - 2bc*cos(A)

<u>Using the formula</u>:  BC² = 15² + 13² - 2*15*13*cos(95)

                                BC² = 427.991

                                BC = √427.991

                                BC = 20.7 units

What is the value of x in the equation 1/5 x-2/3y = 30, when y = 15?
Svetllana [295]

Answer:

The value of x is 200 in the equation 1/5x - 2/3y = 30, when y = 15

Step-by-step explanation:

<u>Given</u>

equation: x - 2/3y = 30

when y = 15

<em>Plug in y:</em>

1/5x - 2/3(15) = 30

1/5x - 10 = 30

<em>add</em> 10 to both sides,

1/5x - 10 + 10 = 30 + 10

1/5x = 40

<em>multiply</em> both sides by 5

1/5x * 5= 40 * 5

x = 200
