1.9x10x10x10+2.3x10x10x10x10
The 2 is in the tenths place so it's 2/10 or two tenths. : )
Answer:
13.3650978628
Step-by-step explanation:
Angle A=180-(Angle B+C)=180-117=63
Here,
b=BC, p=AC & AB=12
Using the relation of cos,
cosx=b/h
cos27=BC/15
15cos27=BC
Using a calculator,
BC=13.3650978628
If you do 6-8 you get -2 so all you have to do is add the 3 and its negative. the answer is .............-32
