So the length will be 18^2-4^2 all rooted. 18 square is 324 and 4 square is 16 and 324-16 is 308 so the answer will be the root of 308 or 2 root 77, at least that is what I think.

Answer:

The length is 17.6 units.

Step-by-step explanation:

Given a right triangle with a leg of 4 units and of hypotenuse 18 units.

we have to find the length of other leg.

Using Pythagoras theorem;

Hypotenuse^2=Base^2+Height^2

The hypotenuse of a right triangle is 18 units, and one of the leg is 4 units.

Let x be the other leg which we have to find out.

Substitute these in above formula we have;

⇒ 18^2=4^2+x^2

⇒ x^2=324-16=308

⇒ x=\sqrt{308}=17.5499\sim 17.6 units

Therefore, the other leg of the right triangle is 17.6 units.

Can you estimate 7533
Oduvanchick [21]

Based on your comment I assume you want to find 7,533 subtracted by 7,200. To estimate this, round 7,533 to the hundreds place, so 7,533 becomes 7,500.

7,500 - 7,200 = 300, using mental math.

Use the following diagram and information to answer the question.
Reika [66]

Answer:

  b)  Julie can use properties of congruent triangles to show that AB≅BC and BC≅CD. Then she can show BC≅AD because opposite sides of a parallelogram are congruent

Step-by-step explanation:

On the assumption that Julie must show all four sides to be congruent, the one remaining step after using the properties of congruent triangles is to show that side AD is congruent to the rest of the sides. Answer choice B describes that.

___

IMO, Julie is finished after she shows∠A≅∠B and AB≅BC, because a parallelogram will be a square if adjacent sides are congruent (makes it a rhombus) and adjacent angles are congruent (makes it a rectangle). A rhombus that is a rectangle is a square.
