here if 20 degree angle is in base line then we would take sin of 20
because sin theta = height / hupotaneous
sin 20 = height/ 10
height = 10 times sin 20 = 10 times *0.34 = 3.4
But if angle 20 in on the line making height of the triangle then the base line of angle 20 degree would be the height of triangle )
we would take : cos 20 =base / hypotaneous
cos 20 = base / hypotaneous
cos 20 = base / 10
base = 10 cos 20 = 10 * 0.93 = 9.3
As per the given question if 20 degree angle lie on horizontal line answer should be 3.4
OR if angle 20 degree lie on vertical line then answer is 9.3
I would help you but the picture is blurry
Answer:
remaining portion is area= area of rectangle- area of semicircle
= 18*14 - 3.14*7^2
=252-154.86
=199.86cm^2
Answer: 198 is your answer:65+66+67 = 198 Hope I helped!
