The measure of arc BCD is

makkiz [27]

Answer:

m∠BCD = 140°

Step-by-step explanation:

ABCD is cyclic quadrilateral. A property of cyclic quadrilateral states that the opposite angles of it sum up to 180°. Here:

m∠A + m∠C =180° and m∠B + m∠D = 180°

So, m∠A + m∠C =180°

m∠A = 40° (given in the question)

40° + m∠C = 180°

m∠C = 180° - 40° = 140°

∴m∠C = m∠BCD = 140°

Answer: 3

Step-by-step explanation:

Given

$f(x)=\dfrac{1}{3}3^x$

$g(x)=2x+4$

For $f(x)$ to be true, the domain is given by observing the graph of two i.e. $x\in (-1.981,3.117)$ . In this range $g(x)$ is greater than $f(x)$ .

From the above domain largest integer that can satisfy the condition is 3.
