Answer:

the second one 9v+36

Step-by-step explanation:

because with the way it set up it wants you to multiply 9 by everything inside of the parenthesis so 9 times v is 9v and 9 times 4 is 36 thus 9v+36 and you also take the addition symbol from inside the parenthesis.

Chord AB subtends two arcs with measures in the ratio of 1:5. Line l is tangent to a circle at point A. Find the measure of the

elena-14-01-66 [18.8K]

Answer:

30°

Step-by-step explanation:

If chord AB subtends two arcs with measures in the ratio of 1:5, then the measure of minor arc is x and the measure of major arc is 5x. Thus,

$x+5x=360^{\circ}\\ \\6x=360^{\circ}\\ \\x=60^{\circ}.$

Thus, the measure of the angle AOB is 60°. Consider isosceles triangle AOB (because AO=BO=radius of the circle). The angles adjacent to the base AB are congruent, thus

$\angle BAO=\dfrac{1}{2}(180^{\circ}-60^{\circ})=60^{\circ}.$

Since line CD is tangent to the circle,

$\angle CAO=90^{\circ}.$

Hence,

$\angle CAB=\angle CAO-\angle BAO=90^{\circ}-60^{\circ}=30^{\circ}.$

54 divided by _____ = -27

Nikitich [7]

54/-2 = -27

First, let's rewrite:

Let x represent the unknown number:

$\frac{54}{x}=\text{ -27}$

$\begin{gathered} \frac{54}{x}\text{ = -27} \\ 54\text{ = -27x} \\ \text{Divide both sides by -27} \\ \frac{54}{-27}=\text{ }\frac{-27x}{-27} \end{gathered}$ $\begin{gathered} 27\times2\text{ = 54} \\ x\text{ = -2 (because we are dividing positive number by a negative number)} \\ So\text{ our answer will be negative} \end{gathered}$

Hence, 54/-2 = -27
