Question

find the other two sides of right angle triangle if hypotenuse is 20 cm and the other two sides of triangle are equal.​

Answer 1

Answer: Mark me as brainliest

Step-by-step explanation:  

Given hypotenuse, h=20cm

Ratio of other two sides, a:b=4:3

Let altitude of the triangle be 4x and base be 3x.

According to Pythagoras theorem,

h

=b

+a

20

=(3x)

+(4x)

400=9x

+16×2

25x

=400

x

=400/25

x

=16

Taking square root on both sides

x=4

so base, b=3x=3×4=12

altitude, a=4x=4×4=16

Hence the other sides are 12cm and 16cm
