Question

hypotenuse = 20 cm
base = 4x
perpendicular = 3x
Find thevalue of 'x'​

Answer 1

Answer:

hypo^2=base^2+perp^2

20^2=4x^2+3x^2

400=16x^2+9^2

400=25x^2

400/25=x^2

16=x^2

√16=x

x=4

hope it helped u

mark me as brainliest

Answer 2

Answer:

h² + b² = hypotenuse ²

(4x)² + (3x)² = 20²

=> 16x² + 9x² = 400

=> 25x² = 400

=> x² = 400/25

=> x² = 16

=> x = √16

=> x = 4.

so, the value of x is 4.
