John needs to cut three strips of wood, 25.5 cm, 15.3 cm, and 9.25 cm long. he has a strip that is 72 cm long. how long will the leftover piece be after he cuts what he needs?

It would be 21.95, because you first have to add the length of the three strips of wood, and you get 50.05, and then you subtract that from the length of the wood that he needs to cut the three strips from.

Add the three strips of cut wood together:

John will need to cut a total of 50.05cm of wood.

Subtract this total from the strip John has:

The leftover piece will be 21.95cm long.

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
