Answer:
x = 25 degrees.
Step-by-step explanation:
By the external angle of a triangle theorem x + <C = 50
But x = <C ( alternate angles).
Therefore 2x = 50
x = 25.

Answer:
19.3 cm
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle B = 71°
Adjacent = 6.3 cm
Hypothenus = BC =?
The length BC can be obtained by using cosine ratio. This is illustrated below:
Cos B = Adjacent / Hypothenus
Cos 71 = 6.3 / BC
0.3256 = 6.3 / BC
Cross multiply
0.3256 × BC = 6.3
Divide both side by 0.3256
BC = 6.3 / 0.3256
BC = 19.3 cm
Thus, Lenght of side BC is 19.3 cm
