Step-by-step explanation:
we know that
The sum of interior angles in a triangle must be equal to 180 degrees
so

solve for x





Answer:
The required volume is 5 ml.
Step-by-step explanation:
Given : In tests for intoxication, blood alcohol levels are expressed as percentages by volume. A blood alcohol level of 0.080% by volume means 0.080 mL of ethanol per 100 mL of blood and is considered proof of intoxication. If a person's total blood volume is 5.0 L.
To find : What volume of alcohol in the blood gives a blood alcohol level of 0.100 % by volume?
Solution :
According to question we use the formula,

The percentage of a blood alcohol level is 0.100%
The total volume of the blood is V=5L=5000 ml.
Substitute the value in the formula,




Therefore, the required volume is 5 ml.
Answer:
Well, with the info I have been given I would say; The L.A of a cylinder is SA+=2(pi)(r)(h).
Step-by-step explanation:
SA=Surface Area
LA=Lateral Area
Pi=3.14
R=Radius
H=Height
V=Volume
LA=2*pi*r*h <-- finds the Lateral Area of a cylinder
SA=LA+2*base or SA=2*pi*r*h+2*pi*r^2<-- finds the Surface Area of a cylinder
V=pi*r^2*h<---- Finds volume of the cylinder
Answer:
Step-by-step explanation:
sin=y/r
cos=x/r
sin=21/29
cos=x/29
x^2+y^2=r^2
x^2+21^2=29^2
x^2+441=841
x=sqrt(841-441)
x=20
cos=20/29
