Question

In the following right triangles, find the length of the unknown sides :​

Answer 1

$\huge \sf {\purple{\underline {\pink {\underline { Answer᭄\ }}}}}$

Δ RST is a right angled triangle ,

So , By pythagoras theoram

RT² = RS² + RT²

RT² = (4.5)² + 6²

RT² = 20.25 + 36

RT² = 56.25

RT = √56.25

Answer 2

$\large\underline\mathbb\blue{ANSWER⤵}$

Given,

TS= 6cm

SR= 4.5cm

To find,

Length of TR

Solution,

As RST is a Right angled traingle,

Applying Pythagores Theorem,

(RT)²=(RS)²+(TS)²

(RT)²=(6)²+(4.5)²

(RT)²=36+10.25

(RT)²=56.25

RT=$\sqrt{56.25}$

RT= 7.5cm

Hope it helps..

Keep smiling..☺
