Answer:
Step-by-step explanation:
A )
a / sinA = c / sinC
sinA = a sinC / c
= 56.2 sin 46.32 / 22.1
= 1.84
The value of sin value of an angle can not be more than 1 so the triangle is not possible .
B )
B = 180 - ( 32.76 + 21.97 )
B = 125.27
a / sin A = c / sin C
200 / sin 32.76 = c / sin21.97
c = 74.82 / .5411
= 138.27 m
b / sin B = a / sin A
b / sin 125.27 = 200 / sin 32.76
b = 163.28 / .5411
= 301.75 m
C )
Area of triangle = 1/2 ac sinB
= .5 x 7.2 x 3.4 x sin 42
= 8.19 sq ft .
Answer:
Plane B is closer.
The distance for Plane A is 7.9 km.
The distance for Plane B is 7.4 km.
Step-by-step explanation:
To find the distance to the tower, altitude must be converted to kilometers. Each 1000 ft is 0.3048 km, so the heights of the planes are ...
-- Plane A: (20 thousand ft)*(0.3048 km/thousand ft) = 6.096 km
-- Plane B: (8 thousand ft)*(0.3048 km/thousand ft) = 2.4384 km
The Pythagorean theorem can be used to find the distance from each plane to the tower:
-- distance = √((ground distance)² + (height)²)
-- Plane A distance = √(5² +6.096²) ≈ √62.16 ≈ 7.9 . . . km
-- Plane B distance = √(7² +2.4384²) ≈ √54.95 ≈ 7.4 . . . km
The distance for Plane B is shorter, so Plane B is closer to the tower.
Horse- 50l
sheep-4l
chicken-200ml
first you have to convert all the symbols into one, so we'll convert liters into milliliters,
1000ml=1l
horse= 50 ×1000=50000ml
sheep=4×1000=4000ml
chicken= 200ml
so now we have to multiply them by the number of animals,
h=50000ml×3=150000ml
s=4000×15=60000ml
c=200×12=2400ml
now add them together,
150000+60000+2400=212400ml
convert it into litres,
212400÷1000=212.4l
answer= 212.4 l
Answer:
1800 mi
Step-by-step explanation:
Recall that (distance) = (rate)(time).
Here, (distance) = (200 mi/hr)(8.5 hr) = 1800 mi

You divide 3/5 and then you get a decimal 0.6. Then you convert it to a percentage
