Answer:
sin x = 0.998
cosx = 0.046
Step-by-step explanation:
<u>Given that:</u>
tan x = 21
where interval of x is .
We know that the trigonometric identity for tan x is:
Comparing with:
Perpendicular = 21 units
Base = 1 unit
As per pythagorean theorem:
interval of x is so values of sinx and cosx will be positive because it is first quadrant where values of sine and cosine are positive.
We know that
So, sine x :
Similarly, value of cos x :
Answer:
Step-by-step explanation:
number of columns of A=number of rows of B
number of rows of A=number of rows of C
