Firstly we calculate the height(h)...,

by using trigonometry ratios

;tan 45° = h/5

;where.. h = 5 tan 45°

;h = 5

Then we calculate the side x...using the height h and the angle of 30°

by also using trigonometry ratios

; sin 30° = 5/x

;where.. x = 5/(sin 30°)

Hence...., x = 10

Answer: x = 10

Answer:

The height of water in the container is 5 cm

Step-by-step explanation:

Here, we want to calculate the height of the water in the container

Mathematically, the volume is :

50 * 30 * h = 1500h cm^3

Also, 7.5 L = 7500 cm^3 = 7.5 L

Let the height be h

1500h = 7500

h = 7500/1500

h = 5 cm
