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
Subtract 153-63=90 and I am pretty sure that's what you have to do
Answer: a< -4 D
Step-by-step explanation:
Answer is 6 you have to use distributive property to combine terms and than you simplify to get the answer<span />
