How to use it, because I don;t know :(

so how to calculate for example angle ABC?

In a triangle ABC, let D and E be the intersections of the bisectors of the angles ABC and ACB with the sides AC and AB, respectively. Knowing that the measures in degrees of the angles BDE and CED are equal to 24 and 18, respectively, calculate the difference in degrees between the measures of...

Do you have an answer?

1 / α + β = 90 2 / it is enough to note that the triangles KNP and MLQ (they have two heights of length "a") so they are isosceles so |∡NMQ| =90 - α/2 and |∡MNP| =90 - β/2 γ=(α + β)/2=45

Hint

Two angles of a square with side protrude beyond a strip of width with parallel edges. The sides of the square intersect the edges of the strip at four points. Prove that the diagonals of the quadrilateral whose vertices are these points intersect at an angle of degrees.

Maybe you have GDC=7x? we at home :)

$\triangle CGD$ is not also isosceles. If only we could prove that $\triangle CGD$ is similar to $\triangle AGC$, if GDC=7x ??

Look page 74.

This is the problem with the 4 point kangaroo competition.

But that equation is hard to solve.

Ok but answer is 10 not 0, so how solve this without wolfram. https://hobbydocbox.com/Board_Games_and_Puzzles/77639583-Annual-ksf-meeting-november-protaras-cyprus.html I've tried to find a trick solution.
