Answer:
cos x = 0.5
Step-by-step explanation:
Using the trigonometric identity
cot x =
Given
sin x cot x = 0.5, then
sin x × = 0.5 ← cancel sin x on numerator/ denominator
cos x = 0.5

Is means equal
of means multiplication
so
20 = 40% x a
40% = 40/100 = 4/10 = 2/5
So
20 = 2/5 x a
Multiply both sides by 5/2
20 x 5/2 = a
10 x 5 = a
a =50
So your final answer is
