The equation of line is y = x. the midpoint of bc is (a + c, b). does the midpoint of bc lie on ? why or why not? no, because b does not equal a + c no, because (a + c) does not equal b yes, because b = a + c yes, because (a + c) = b

yes, because (a+c) =b

Step-by-step explanation:

Given that equation of the line is y=x.

B and C are two points lying on this line.

Midpoint of B and C are given as (a+c, b)

From this we see that using midpoint formula

Since both points lie on y=x, we get

x1=y1 and x2=y2

So x1 = a+c and 2y1 = 2b or y1 =b

Since x1=y1, we have a+c =b

i.e. the coordinates of mid point satisfy the equation y=x

Hence answer is

yes, because (a+c) =b

yes because (a + c) = b

Step-by-step explanation:

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
