What is mbd? 154 112 168 126

what's mbd

The correct option is B. 112°  

Step-by-step explanation:

In the given figure : m∠C = 14° and measure of arc AE = 140°

Now, we need to find the measure of arc BD

So, To find the required arc measure :

Using the exterior angles theorem of a circle : The angle formed in the exterior to the circle by the major and minor arcs is twice the difference of two arc measures

⇒ 2 × m∠C = measure of major arc AE - measure of minor arc BD

⇒ 2 × 14 = 140 - measure of minor arc BD

⇒ Measure of minor arc BD = 140 - 28

⇒ Measure of minor arc BD = 112°

Therefore, The correct option is B. 112°

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
