construction in exercises 53-55, use the photograph of a roof truss.
(53.) in the roof truss, bg bisects zabc and z def,
m zabc = 112, and zabc = zdef. find the
measure of the following angles.
a. mzdef
b. m zabg
c. m2 cbg
d. mz deg
54. in the roof truss, gb bisects dgf.
find m2dge and mzfge.
55. name an example of each of the
following types of angles: acute,
obtuse, right, and straight.
1.4 measure and cla

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

answer: it is 8

step-by-step explanation:

you know why its 8

i dont know

step-by-step explanation:

the reason i dont know is because i have not taken this class and for that reason i haven't learned this stuff

hope i could

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
