Answer:
it is in standard form?
Step-by-step explanation:
To find x:
use the formula: cos° = adajcent/hypo
cos 37° = x/ 16
answer: 12.8
The other length:
use the same formula
cos 57° = y/16
answer: 8.7
(hope this helps)
Answer:
B' (1, 2 )
Step-by-step explanation:
Since the centre of dilatation is the origin then multiply the coordinates of B by the scale factor.
B (4, 8 ) → B' (4 × 
, 8 × ) → B' (1, 2 )
Answer:
first one
Step-by-step explanation:
The objective is to get the variable (x) alone. To do this start be subtracting 3. What you do to one side you have to do to the other so you have to subtract three from the other side of the equal sign as well. So now you have:
20x= 17-3 subtract the 3 to get 20x=14
Now because the 20 is attached to the x In order to get the x alone you have to divide by 20:
20x/20. =14/20 divide 14 by 20
X=.7 or x=7/10
