Question

in the triangle,angel RST IS 90°.RS=4cm and ST=3cm . What is the length of RT

Answer 1

Answer:

RT=5 cm

Step-by-step explanation:

given: S =90°

RS=4cm

ST=3cm

By Pythagoras therome,

$tr { }^ {2} = ts {}^{2} + rs {}^{2}$

$tr { }^{2} = 4 {}^{2} + 3 {}^{2}$

$tr {}^{2} = 16 + 9$

$tr = \sqrt{25}$

$tr = 5cm$
