B) 57.4+x=67
Step-by-step explanation:
We take the amount in the piggy bank. Then we take the amount spent and add it to the amount she has left. These two amounts should be equal

Answer:
it will be the last one bc 18d is on the chart
Answer:
see explanation
Step-by-step explanation:
Given
tan a = 
= 
We require the hypotenuse h
Using Pythagoras' identity
h² = 9² + 40² = 81 + 1600 = 1681 ( take square root of both sides )
h = 
= 41 , thus
sin a = 
= 
cos a = 
= 
2.750 + 0.003 + 0.158
= 2.753 + 0.158
