m<ABD = 52                               Given

BC bisects <ABD                        Given

m<ABC =  m<CBD                      Definition of angle bisector.

m<ABC +m<CBD = m<ABD        Angle addition postulate.

m<ABC +m<CBD = 52                Substitution

m<ABC + m<ABC= 52                Substitution

2m<ABC = 52                             Combining like angles

m<ABC = 26                                Division property of equality.  

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
