Answer:
The correct answer by solving question no 1 is
a=(d-c)/b
Step-by-step explanation:
ab+c=d
or,ab=d-c
Therefore,a=(d-c)/b
Answer:
B. 0.72
Step-by-step explanation:
8/11 = 0.72
It all depends upon what other things are given If hypotenuse is not given, in cosine or reciprocals are useless. In that case only tan and cot will be equally convenient if adjacent sides are given.
Answer:
0.866
Step-by-step explanation:
If tan x = 1.731 then sin x =
Given data
tan x = 1.731
x= tan^-1 (1.731)
x= 59.98°
x= 60° approx
Aso
sin x=??
substitute
sin 60°= 0.866
Hence the answer is 0.866
