Which pair of points have equal x-coordinates? On a coordinate plane, point T is (4, 6), point S is (5, negative 6), point R is (negative 5, negative 7), and point Q is (negative 5, 6). points Q and R points Q and T points R and S points S and T

Given: ∆mop p∆mop =12+4 3 m∠p = 90°, m∠m = 60° find: mp, mo

If tan2a=cot(a+60), find the value of a, where 2a is an acute angle

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18}, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.
