Answer:
sin 70° = cos (90° - 70°)
Step-by-step explanation:
You need to use the trigonometric ratios which states that:

sin 70° = cos 20°
If he has completed 3/5 he needs to go (1-3/5 ) 2/5 yet
4000* 2/5 =1600
He needs 1600 points
Answer:
Step-by-step explanation:
Let the numbers be y, y+2, y+4
3(y+2)=153
3y+6=153
3y=153-6
3y=147
y=49
y+2=51
y+4=53
9, 15, and 21 they are all odd numbers but are not all only divisible by 1; therefore, they are not prime numbers
