Given that 20 − (y − x) = 30 − (x − y), and x = 4, what is the value of y ?

The reflexive property of congruence lets you say that ∠pqr ≅

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?

Find the value of x in each case. give reasons to justify your solutions! d q ∈ pr
