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

Answer:
3.92*10^3mm
Step-by-step 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.
Answer:
3919 mm
Step-by-step explanation:
Length of hypotenuse = 7900 - 900 = 7000 mm
Base = 5800 mm
Let the height of the triangle be h mm
Therefore, by Pythagoras theorem:
[tex] h = \sqrt{7000^2 - 5800^2} [/tex]
[tex] h = \sqrt{49000000- 33,640,000} [/tex]
[tex] h = \sqrt{15,360,000} [/tex]
[tex] h = 3,919.18359\: mm[/tex]
[tex] h = 3,919\: mm[/tex]
