How do you solve this??? Someone help. We just started learning Pythagoras Theorems..

ira [324]

Answer:

It means length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

Step-by-step explanation:

to solve this...we think that distance from ben to church is x...now a triangle is formed.

length of the hypotenuse is 13cm

${13}^{2} = {8}^{2} + {x}^{2}$

$169 = 64 + {x}^{2}$

$169 - 64 = {x}^{2}$

$105 = {x}^{2}$

$\sqrt{105} = x$

$x = 10.246950766$
