Evaluate each expression.
1) 3(6+7)

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.

Match the one-to-one functions with their inverse functions.
