Hi there!
Th' following triangle is divided into 2 sub-triangles!
• In 1ˢᵗ triangle :-
tan 45° = [tex]\dfrac {b}{p}[/tex]
⇒ 1 = [tex]\dfrac {5}{p}[/tex]
⇒ [tex]p[/tex] = 5
• In 2ⁿᵈ triangle :-
cos 30° = [tex]\dfrac {p}{h}[/tex]
⇒ [tex]\dfrac {1}{2}[/tex] = [tex]\dfrac {5}{x}[/tex]
⇒ [tex]x[/tex] = 2 × 5
⇒ [tex]x[/tex] = 10
Hence,
Th required answer is 10 units.
~ Hope it helps!
