Question

two sides being given, calculate the third side marked by a letter in each right angled triangle
please step by step explanation​

Answer 1

Answer:

x= 12units

Step-by-step explanation:

as it is a Right angled triangle we can apply Pythagoras Theorem

that is base²+perpendicular ²= hypotenuse²

here base is x

perpendicular is 9

hypotenuse is 15

By applying Pythagoras Theorem it is

x²+9²=15²

x²= 15² – 9²

x²=225–81

x²=144

x=√144

x=12 units

Answer 2

Answer:

(base)^2+(height)^2=(hypotenuse)^2

Step-by-step explanation:

${9}^{2} + {x }^{2} = {15}^{2} \\ 81 + {x}^{2} = 225 \\ {x }^{2} = 225 - 81 \\ \\ {x}^{2} = 144 \\ x = 12$
