28ft, 4ftx10ft. 2 4ft edges and 2 10ft edges. (2x4) + (2x10)= 28 ft
Answer:
The value of x is 17°.
Step-by-step explanation:
The two exterior angles on the same side of the transversal are always supplementary.
Therefore, if the measure of two exterior angles on the same side of the transversal are 3x and 7x+10, then we can write
3x + (7x + 10) = 180°
⇒ 10x = 180° - 10° = 170°
⇒ x = 17°
Therefore, the value of x is 17°. (Answer)
Applying implicit differentiation, it is found that dy/dt when y=π/4 is of:
a-) -√2 / 2.
<h3>What is implicit differentiation?</h3>
Implicit differentiation is when we find the derivative of a function relative to a variable that is not in the definition of the function.
In this problem, the function is:
xcos(y) = 2.
The derivative is relative to t, applying the product rule, as follows:
Since dx/dt=−2, we have that:
When y = π/4, x is given by:
xcos(y) = 2.
Hence:
Since cot(pi/4) = 1, we have that:
Which means that option a is correct.
