You can just simplify to make an equivalent equation:

(2)(3x + 8) = 5 ⇒ 6x + 16 = 5

Answer:

$\boxed{\bf~6x + 16 = 5}$

Answer

x = 8

Explanation

㏒₂ (3x + 8) = 5

5 =㏒₂ 2⁵.

∴ ㏒₂ (3x + 8) = ㏒₂ 2⁵

If the right side of the equation above is equal to the left side, then it is true to say that;

(3x + 8) = 2⁵

3x + 8 = 32

3x = 32 - 8

3x = 24

x = 24/3

= 8

Answer:

111°

Step-by-step explanation:

All these are parallel lines, so the 36° angle is equal to the 36° angle inside the big triangle because they are vertically opposite.

Ignore the line cutting between 45° and the 30° and consider it as one triangle
Add them to get 75°
Now you have two known angles 75° and 36°
To get angle x add 75° and 36° to get 111°
Because x° is an exterior angle and exterior angles equal to the sum of interior angles opposite it inside the triangle.
