Answer:
<h2><em><u>ᎪꪀsωꫀᏒ</u></em></h2>
➪x= 3
Step-by-step explanation:
4x-(8-x)-2=9x-20+x-5
=> 4x-8+x-2 = 9x+x-5
=> 5x-10 = 9x-20+x-5
=> -10+5 = 10x-20-5x
=> -5+20 = 5x
=> 15 =5 x
=> 15/5 = x
=> 3 = x
Try these solutions:
<u>Task 1.</u>
a) the required angle is arctan(CG/AC);
b) according to the condition CG=AE=11.4 (cm.);
c) BC=EH=9.6 (cm.), then

d) the required angle is:

Answer: 29°
<u>Task 2.</u>
a) the required angle is EFV (see the attached picture): arctan(EV/FE);
b) to calculate FE: FE=0.5AB=7.25 (cm.);
c) to calculate EV:

d) to calculate the required angle:
m(∠EFV)=arctan(13.80996/7.25)=arctan(1.9048)≈62.302°=62°.
Answer: 62°
