For lines a, c,and d, Line c is parallel to line d and m<1=55. Part A for the given diagram use the measure of <1 to find the measure of the remaining seven angles.

Part b in two or more complete sentences explain the relationship between angle pairs a)<1 and <7 and b)<1 and <2 in your explanation include how how you couculated each of the angle meaures in the special angle pairs

answer: was that a question or answer?

step-by-step explanation:

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

answer: i think it is (1,-2)

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
