Answer :-  An exterior angle is created by extending one side of a triangle.


Explanation:-

Let ABC a triangle with interior angles ∠A, ∠B and ∠C and one of its side AB is extended to a point P such that a new angle ∠ACP is formed outside the triangle ABC named as exterior angle of ABC.

⇒∠BCA and ∠ACP are supplementary angles.

Also the measure of exterior angle is equal to sum of the opposite interior angles of a triangle.

Answer:

1680 in^3

Step-by-step explanation:

SO you got the triangle

24*10=240

240/2=120

now we just need to find the area

There is a formula but I think this is easier

So theres a rectangle with a length of 14

So if you think of the triangle as the base, you just need 14 triangles stacked up to make up the volume

So 120*14=1680

So the volume is 1680

How do you solve substitution problems in Pre Algebra
Rus_ich [418]
You multiply both of the equations until you have two of the same term the same like for example, say I have 4x and 5x. You want to multiply until both have the same number, so multiply 5x by four, then multiply 4x by five, and you will get 20x, then both of those cancel out and you will be left with the other variable, and you just solve like a normal equation.

Can you construct a triangle that has side lengths 2 yd, 9 yd, and 10 yd?
yan [13]

Yes


The rule to check if a triplet of numbers can represent the sides of a triangle is the following: the sum of the length of two sides must exceed the third one.


This happens for all possible couples in your case:


2+9=11>10


2+10=12>9


9+10=19>2
