How do you find similar triangles (equation?)

Mathematics

Irina-Kira [14]3 years ago
6 0

Two triangles are similar if they have:

<span>all their angles equalcorresponding sides are in the same ratio</span>

But we don't need to know all three sides and all three angles ...two or three out of the six is usually enough.

There are three ways to find if two triangles are similar: AA, SAS and SSS:

Which mathematical statement matches the vector operation shown in the geometric representation?
Sunny_sXe [5.5K]

Answer:

First Option v+w = u

Step-by-step explanation:

To graphically add two vectors a and b using the -tail and tip-method, you must draw the tail of b at the tip of the vector a. Then you must draw a line that goes from the tail of a to the tip of b. This line represents the sum of a + b.

In this problem, notice that the tail of the vector w is on the tip of the vector v. The line that joins the tail of v with the tip of w is u.

Therefore we can say that v + w = u.

The answer is the first option

Answer:

  38 square inches

Step-by-step explanation:

The figure is a quadrilateral with one pair of parallel sides. That means it is a trapezoid, so the area formula for a trapezoid is applicable.

  A = (1/2)(b1 +b2)h

The two parallel bases are 7 in and 12 in. The height is the perpendicular distance between them, 4 in. So, the area is ...

  A = (1/2)(7 in +12 in)(4 in) = (1/2)(19 in)(4 in)

  A = 38 in²

The area of the trapezoid is 38 square inches.
