Answer:

Add 2 to each side

x=1/2

Step-by-step explanation:

(3√8x - 2 )= 4

Add 2 to each side

(3√8x - 2 +2= 4+2

3√8x = 6

Divide each side by 3

3/3√8x = 6/3

√8x = 2

Square each side

(√8x)^2 = 2^2

8x = 4

Divide each side by8

8x/8 = 4/8

x = 1/2

Given: sin theta=2/3 and is in the second quadrant; evaluate the following expression. sin 2 theta

Dmitry [639]

Answer:The answer to your question is 3. 0

Step-by-step explanation:

Process

1.- Find the cos a

Opposite side = 5

Hypotenuse = 13

Adjacent side = ?

Adjacent side² = 13² - 5²

= 169 - 25

= 144

Adjacent side = 12

cos a = 12/13

2.- Find the sin b

sin b = 5/13

3.- Use the formula below to find sin(a + b)

sin (a + b) = sina cosb + sin b cos a

- Substitution

sin (a + b) = (5/13)((-12/13) + (5/13)/12/13)

- Simplification

sin (a + b) = -60/169 + 60/13

- Result

sin(a + b) = 0
