Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180 for B
B = 180° - (90 + 39)° = 180° - 129° = 51°
Using the tangent and sine ratios in the right triangle for b and c
tan39° = 
= 
Multiply both sides by b
b × tan39° = 27 ( divide both sides by tan39° )
b = 
≈ 7.5 ( to the nearest tenth )
sin39° = 
= 
Multiply both sides by c
c × sin39° = 27 ( divide both sides by sin39° )
c = 
≈ 28.0 ( to the nearest tenth )
Answer:
His distance walked is 13 km
Calvin's displacement is 5 km south and 8 km east.
Step-by-step explanation:
5 km + 8 km = 13 km
Because South and East are perpendicular, they do not contradict each other, such as North and South, or East and West.
I hope that this helps! :)
