Set up a proportion 
4      368
--- =  ---- 
5        x
then cross multiply
 
368*5=4x
and divide both sides by four
92*5=x
460=x

Smaller is 4 units

4 units=368
divide both sides by 4
1unit=92
times both sides by 5 since 5 units=big
5unit=460

Please help me with this pleaseee

Answer:

x = 88.2

Step-by-step explanation:

The angle at the top of the triangle = 90° - 10° = 80°

and the left side of the triangle is x ( opposite sides of a rectangle )

Using the tangent ratio in the right triangle

tan80° = \frac{opposite}{adjacent} = \frac{500}{x}

Multiply both sides by x

x × tan80° = 500 ( divide both sides by tan80° )

x = \frac{500}{tan80} ≈ 88.2
