Question

please help me with this question

Answer 1

Answer:

x= 6

Step-by-step explanation:

Pythagoras theorm : H² = B² + P²

here h is huypotenuse. b is base ans p is perpendicular

now put the value of h,b, and p

H² = B² + P²

⇒(10)² = (x)² + (8)²

⇒100 = x² + 64

⇒x² = 100-64

⇒x² = 36

⇒x = √36

∴x= 6

Answer 2

Answer:

x = 6

Step-by-step explanation:

Labelling the given triangle ABC

in triangle ABC,

angle ABC = 90 degrees, Let AC be hypotenuse

Therefore by pythagoras thm,

$ac {}^{2} = ab {}^{2} + bc {}^{2}$

$10 {}^{2} = 8 {}^{2} + bc {}^{2}$

100 = 64 + BC^2

BC^2 = 100 - 64

= 36

Therefore,

BC = 6 (square rooting on both sides)
