English: Let ABC be a right triangle at A with AB=2, AC=3 and altitude AE a) Prove that triangle ABC is similar to triangle EBA
b) The bisector of angle ABC intersects AC at F. Calculate the length BF

Vietnamese: cho tam giác ABC vuông tại A có AB=2, AC=3 và đường cao AE
a) chứng minh tam giác ABC đồng dạng với tam giác EBA
b) tia phân giác của góc ABC cắt AC tại F. Tính độ dài BF

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

can you make your screen more see able?

then i might be able to .

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
