SCORPION-xisa [38]

Answer:

4.891

its side b (opposite side of the 50 degree angle)

Step-by-step explanation:

side c = 6

angle A is 20 side a (opposite side) = 2.184

angle B is 50 side b (opposite side) = 4.891

angle C is 110 side c (opposite side) = 6

1.

get third angle

50 + 20 = 70

180 - 70 = 110

third angle C is 110

2.

get side a

sin A/a = sin C/c

a/c = sinA/sinC

a = c * sinA/sinC

a = 6 * (sin20/sin110)

get sin in degrees

a = 6 * (.342/.9397)

a = 2.184

The trigonometric ratios are used for right angle triangle.The basic rule to followed is SOH CAH TOA

SOH means Sinx=opposite/Hyp.
CAH means Cosx = adj./Hyp.
TOA means Tanx = Opp./Adj.

Opposite is the side opposite to the acute angle of the right triangle.

<span>Adjacent is the side Adjacent to the acute angle of the right triangle.
