Answer:

x=4

Step-by-step explanation:

2(10 -6x)=x -8x

Multiply 2*10 and 2*-6x

20-12x=x-8x

Add 12x

20=x-8x+2x

Combine x and -8x

20=-7x+12x

Combine -7x and 12x

20=5x

Divide 5x/5 and 20/5

4=x

So x=4

Step-by-step explanation:

2(10 -6x)=x -8x

20 - 12x = x - 8x

20 = x - 8x + 12x

20 = 5x

20 / 5 = x

x = 4

How can I find a? (Trigonometric Ratios)

earnstyle [38]

Step-by-step explanation:

Hey there!

Use cos ratio to find the value of 'a'.

As per given, we can state that it is a Right angled triangle, so taking 38° reference angle.

We get;

p = AC

b = 6

and h= a

Here, Use the value of b, h and 38° angle to find the value of a.

$\cos(38° ) = \frac{b}{h}$

$\cos(38°) = \frac{6}{a}$

$0.7881 = \frac{6}{a}$ [ cos(38°=0.7881]

$0.7881a = 6$

$a = \frac{6}{0.7881}$

Therefore the measure of a is 7.61 Or 8.

Hope it helps..
