If arc mdc equals 4x - 2 the arc mbc is equal to 20° and angle a measures 12°. find the value of x.

The value of x is 11.5.

Step-by-step explanation:

Since, when one tangent and one secant intersect outside a circle, then the measure of the intersection angle is half of the difference of the intercepted arcs,

In the given diagram,

AD is the secant and AC is the tangent of the circle,

Also, AD and AC intersect at A,

Thus, by the above statement,

Here,

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
