Answer:
#1) Angle measure of B
The angles in a triangle should add up to 180. Since we know the other two angle measures, we can subtract it from 180. (180-45-15= Angle B)
Angle B= 120
#2) Length of segment BC
I would use the Law of Sines. So, sin120/200 = sin45/BC
Then cross multiply and divide.
Segment BC= 163.3
#3) Length of Segment BA
Again, I would use the Law of Sines. Same process, sin120/200 = sin15/BA
Segment BA= 59.8
The Parkland formula is
V = 4mA
where
V = volume of replacement fluid (mL) required within the first 24 hours after a burn injury,
m = body mass, kg
A = percent of body surface area covered with burns.
The first half of the fluid should be delivered in the first 8 hours.
Because we are concerned with fluid replacement within the first 8 hours, the Parkland formula is valid to be used.
Given:
m = 75 kg
A = 40%
Therefore
V = 4*75*40 = 12,000 mL = 12 L
This is the fluid replacement required in the first 24 hours.
Because half of this amount should be delivered in the first 8 hours, the amount of fluid replacement is
6,000 mL in 8 hours, or
6000/8 = 750 mL per hour.
Answer: 750 mL every hour
Hello,
1)
sin x=3/5==>x=126.869897...° (since in quadrant II)
2)==>cos x<0
cos x=-√(1-sin ² x)=-√(1-9/25)=-4/5
tan x=(3/5)/(-4/5)=-3/4
cotg x=-4/3 =1/tan x
sec x=1/cos x=-5/4
cosec x=1/sin x=5/3
Answer:
C
Step-by-step explanation:
A regular octagon has 8 lines of symmetry.
The point of intersection of the lines of symmetry of a regular octagon is the point of symmetry.
