Answer 1

Sᴇᴇ Dɪᴀɢʀᴀᴍ ɪɴ Aʙᴏᴠᴇ Aᴛᴛᴀᴄʜᴍᴇɴᴛ

Given :

• Measure of A = 3.5 cm
• Measure of B = 7.9 cm
• Measure of C = ?

What To Find :

• Measure of C ?

Solution :

$\boxed{\sf \large\rm\purple{Using \: \: Pythagoras \: \: Theorem} \rm \:}$

$\begin{cases}\large\bf\red{ \implies} \rm \:C² \: = \: \sqrt{A² + B²} \\ \\ \large\bf\red{ \implies} \rm \:C² \: = \: \sqrt{3.5 \: ² + 7.9 \: ²} \\ \\ \large\bf\red{ \implies} \rm \:C² \: = \: \sqrt{12.25 \: + \: 62.41} \\ \\ \large\bf\red{ \implies} \rm \:C² \: = \: \sqrt{74.46} \\ \\ \large\bf\red{ \implies} \rm \:C = \: 8.6 \end{cases}$

• Measure of C is 8.6

Answer 2
