Question

First person to solve gets fan, and help in another subject.

Answer 1

Here is the needed theorem:

Triangle Angle Bisector Theorem: If a ray bisects an angle of a triangle, then it divides the opposite side into segments that are proportional to the sides that formed the angle.

Answer 2

I think both triabgle are equal because of side-angle-side

Answer 3

>>I think both triabgle are equal because of side-angle-side

Which sides and which angles are congruent to get the two triangles congruent by SAS?

@isaidavila

We don't know anything about the angles with vertex D.

Answer 4

But it suppose to be 90 degrees

Answer 5

5.7/AC = 4.9/4.9

5.7/AC = 1

AC = ? @sbuck98

Answer 6

5.7? @directrix

Answer 7

@Directrix

Answer 8

@sbuck98 Correct.

Answer 9

>>But it suppose to be 90 degrees

Why?

Answer 10

Triangle Bisector Theorem: If a ray bisects an angle of a triangle, then it divides the opposite side into segments that are proportional to the sides that formed the angle.

Answer 11

x/5.7 = 4.9/4.9 where x = AC

x =

Answer 12

This problem came up on my notifications. So, let's finish it.

Answer 13

i already did that one a while back

Answer 14

I need the one I tagged you in

Answer 15

And, the answer is x = ?

Answer 16

Solve this:

x/5.7 = 4.9/4.9 where x = AC

Answer 17

5.7
