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 .
