Which equation can be used to find x, the length of the hypotenuse of the right triangle

pythagoras equation can be used to find x, the length of the hypotenuse of the right triangle.

step-by-step explanation:

pythagoras theorem states that in a right angled triangle abc with right angle at b , the sum of square of side and perpendicular is equal to the square of hypotenuse.

that is

where ac is hypotenuse , bc is base and ab is perpendicular.

we are given hypotenuse = x

we can find the hypotenuse using this if we are given other two sides.

then it becomes,

.

thus, pythagoras equation can be used to find x, the length of the hypotenuse of the right triangle.

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
