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
