Answer:

B 84

Step-by-step explanation:

Angle COB = 96 (Angle CDB x2)

Lets split Quadrileteral ABOC into 2 equal parts.

Angle ABO = 90 (tangent segment of circle)

Angle AOB = 96/2 = 48

Angle OAB = 180 - 90 - 48 = 42

Angle A = Angle OAB x 2 = 42 x 2 = 84

Therefore Answer is B.

zepelin [54]

3 & 6 - LCM = 3. 3's multiples are 3, 6, 9,12, 16, etc. 6's multiples are 6, 12, 18, etc. therefore, the least common multiple is 6.
GCF - 3's factors are 1, 3, and 6's factors 1, 2, 3. so the greatest common factor is 3.

Write an equation of the line passing through (-2,4) and (3,5). Give the answer in standard form.The equation of the line in sta

Alecsey [184]

Start finding the slope of the line

$\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ \text{then,} \\ m=\frac{5-4}{3-(-2)} \\ k=\frac{1}{5} \end{gathered}$

using one of the points find the intercept and the standard form

$\begin{gathered} (-2,4) \\ 4=\frac{1}{5}(-2)+b \\ b=4+\frac{2}{5} \\ b=4.4 \end{gathered}$

the equation of the line is

$y=\frac{1}{5}x+4.4$
