Please help me on this

Answer 1

$\sf\pink{c\:=\:45\:kilometres}$ ✅

Step-by-step explanation:

$\sf\purple{Using\:Pythagoras\:theorem, \:we \:have}$

$({Perpendicular})^{2} + ({Base})^{2} = ({Hypotenuse})^{2} \\ ➪\:( {36 \: km})^{2} + ({27 \: km})^{2} = {c}^{2} \\ ➪ \: {c}^{2} = 1296 \: {km}^{2} + 729 \: {km}^{2} \\ ➪ \: {c}^{2} = 2025 \: {km}^{2} \\ ➪ \: c \: = \sqrt{ {2025 \: km}^{2} } \\ ➪ \: c \: = 45 \: km$

${\boxed{\mathcal{\red{Therefore,\:the\:length\:of\:the\:hypotenuse\:is\:45\:km.}}}}$

$\boxed{Note:-}$

• Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides."
