Answer fast plsssssssssss​

Answer 1

Step-by-step explanation:

Pythagoras theorem

x^2=4^2+3^2

x^2=16+9

x^2=25

x=√25=5 cm

Answer 2

$\sf \bf \huge {\boxed {\mathbb {QUESTION}}}$

$\tt Find\:x$

$\sf \bf \huge {\boxed {\mathbb {ANSWER}}}$

$\sf \bf {\boxed {\mathbb {GIVEN}}}$

• $\sf \bf AB=3\:cm$
• $\sf \bf BC=4\:cm$

$\sf \bf {\boxed {\mathbb {TO\:FIND}}}$

• $\sf \bf Value \:of \:x$

$\sf \bf {\boxed {\mathbb {SOLUTION}}}$

$\sf \bf In\:\triangle ABC, \angle B={90}^{\circ}$

${\color {gold}\underline {\sf By\: pythagoras\: theorem}}$

${\boxed {\boxed{\boxed {\color {blue} {\sf \bf {AC}^{2}={AB}^{2}+{BC}^{2}}}}}}$

${\underbrace {\overbrace {\color {orange} {\bf Substitute \:the \:values}}}}$

$\sf \bf \implies {\Big(x\Big)}^{2}={\Big(3\Big)}^{2}+{\Big(4\Big)}^{2}$

$\sf \bf \implies {x}^{2}=9+16$

$\sf \bf \implies {x}^{2}=25$

$\sf \bf \implies x=\sqrt{25}$

$\implies{\boxed {\boxed {\color {aqua} {\sf \bf x=5\:cm}}}}$

${\underbrace {\color {red} {\underline{\overline {\color {red} {\sf \therefore The\:value \:of \:x\:is\:5\:cm}}}}}}$
