Respuesta :

you use pythagoras for this.
a^2 +b^2= c^2
11^2 +6^2 =157
(square root) 157 = 12.5 (1 d.p)


Using Pythagorean theorem

[tex]\\ \sf\longmapsto H^2=P^2+B^2[/tex]

[tex]\\ \sf\longmapsto H^2=11^2+6^2[/tex]

[tex]\\ \sf\longmapsto H^2=121+36[/tex]

[tex]\\ \sf\longmapsto H^2=156[/tex]

[tex]\\ \sf\longmapsto H\approx12.33[/tex]
