Step-by-step explanation:
90 degree - 22 degree = 68 degree
use sin rule
sin90/x = sin68/56
x =60.4 degree
What are you talking about, can I see a picture
2(i).
(3y-20)+(4x-5)+(x+y-10)+(2x+5)=360 (Angles sum of it trapezium)
3y-20+4x-5+x+y-10+2x+5=360
7x+4y=390
(Shown)
2(ii).
(3y-20)+(2x+5)=180 (Interior Angles, Parallel Lines)
2x+3y=195
(Shown)
Hope it helps : )
Answer:
