Here's the solution,

The given triangle is a right angled triangle,

So, by Using Trigonometry :

=》

\sin(30)  =  \dfrac{x}{13}

=》

\dfrac{1}{2}  =  \dfrac{x}{13}

=》

x =  \dfrac{13}{2}

=》

x = 6.5

Answer:

1. a = 2

2.  x = 12

3. w = 2

Step-by-step explanation:

1. ok so 2a/5 we would want to separate it to 2/5 and a/5

2/5 x a/5 = 2a/5

next we want to subtract 2/5 from 8/10

8/10 - 2/5 or 8/10 - 4/10 = 4/10

now you have a/5 and 4/10

a/5 = 4/10

now you multiply each side by 5

a/5 x 5 = a

4/10 x 5 = 20/10 or 2

a = 2

2. ok so the x is kinda on it's own for this one but we still wan to get the x and the other numbers on opposite sides

1/16x + 1/4 - 1/4 = 1/16x

1/2 + 1/4 = 3/4

now we do that same last step

1/16x / 1/16 = x

3/4 / 1/16 = 12

x = 12

3. ill do one more and if you need more help just tell me

for this on we have the w on both sides so we have to get the variable(w) and the numbers on opposite sides

2w - 2 + 2 = 2w

1/2w + 7 - 1/2w = 7

2w + 1/2w = 5/2w or 2 1/2w

7 - 2 = 5

now we have to divide each side by 5/12 or 2 1/2

5/2w / 5/2 = w

5 / 5/2 = 2

w = 2
