Answer:
Perpendicular(p)=21
base(b)=20
hypotenuse(h)=29
Step-by-step explanation:
Now by using the formula:
cos A=b/h
i.e 20 by 29
Answer:
See below.
Step-by-step explanation:
The 4 might be:
-1.9 - 3/2 , -1.8 and - 9/8.
Start by plugging 0 into the equation and see which ones give you 350 back. Those equations are the right ones,
