In a 30°-60°-90° triangle, the sides occur in a ratio of 1 to √3 to 2. In this case, <em>x</em> is half the length of the hypotenuse, so <em>x</em> = 4.
Or, using trig,
cos(30°) = <em>x</em>/8
<em>x</em> = 8 cos(30°) = 8 (1/2) = 4
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
Answer:
Cost of car including VAT = $17,700
Step-by-step explanation:
Given:
Cost of car without VAT = $15,000
Rate of VAT = 18%
Find:
Cost of car including VAT
Computation:
Cost of VAT = Cost of car without VAT x Rate of VAT
Cost of VAT = 15,000 x 18%
Cost of VAT = 15,000 x 18
Cost of VAT = $2,700
Cost of car including VAT = Cost of car without VAT + Cost of VAT
Cost of car including VAT = 15.000 + 2700
Cost of car including VAT = $17,700
