Answer:
75°
Step-by-step explanation:
firstly, use the pythagoras theorem
Square root(8²-2²) = 7.75
Then, use sine
sine A= 7.75/8
Sine A=0.9688
A= (sine power of -1) x (0.9688)
A=75.63
B as if you plug the co-ordinates into the equation and it equals 10: (3x4)-2= 12-2 =10
A doesn't work as the answer is 20
C doesn't work as the answer is 14
D doesn't work as the answer is -20
