Question

Could someone please help me with this? We are meant to use Pythagoras theorem to solve to solve this question

Answer 1

3919 mm

Explanation:

Length of hypotenuse = 7900 - 900 = 7000 mm

Base = 5800 mm

Let the height of the triangle be h mm

Therefore, by Pythagoras theorem:

`h = √(7000^2 - 5800^2)`

`h = √(49000000- 33,640,000)`

`h = √(15,360,000)`

`h = 3,919.18359\: mm`

`h = 3,919\: mm`

Answer 2

3.92*10^3mm

Explanation:

In the diagram it gives you 7900mm. There is a figure which was given underneath written 900mm. use 7900 to subtract 900 you will get 7000. Then you can use the Pythagoras theorem to solve it, with a= height, b=5800mm and c=7000mm where, a^2+b^2=c^2.
