Step-by-step explanation:

↓↓↓↓↓↓↓↓↓↓↓↓

Multiplication property of equality is multiply both sides of an equation by the same number does not change the equation.

$\frac{x}{2}=6$

multiply two both sides

$\frac{2x}{2}=6*2$

simplify

6*2=12

12/2=6

12/6=2

2*6=12

x=12

Hope this helps!

8.5 cm

Step-by-step explanation:

Angles of the triangle:

x+2x+3x= 1806x= 180x= 3030°, 60° and 90°

Right triangle as it has 90° angle

Sides are a, b and 19 cm

sin 30°= a/19 ⇒ a= 19 sin 30°= 19*0.5= 8.5 cm = shortest sidesin 60°= b/19 ⇒ b= 19 sin 60°= 19*0.866= 16.45 cm
