Adjacent and hypotenuse are given so use cosine.
Cos28= 11/x
12.46 is your answer (I rounded)
Answer:
Step-by-step explanation:
we know that
----> by trigonometric identity
we have
substitute
Remember that
If the sine of angle theta is positive, then the angle theta lie on the I Quadrant or II Quadrant
therefore
If the angle theta is on the I Quadrant the cosine will be positive
If the angle theta is on the II Quadrant the cosine will be negative
Answer:
If a function is given in the form of f(x) = ax² + bx + c, then value of x is "input" and the value of the given function for x will be "output". Means if we put the value x = 2 then 2 is the input and f(2) will be the output of the function.
Step-by-step explanation:
3pi+8(t-pi)-4t
=3pi+8t-8pi-4t
=-5pi+4t
