Answer:
DC= 32.3 units
Step-by-step explanation:
Use Pythag theorem to find BC first
15 ^2 + BC ^2 = 22^2 then BC = sqrt 259
Then use the Pythagorean Theorem again to find DC
DC^2 = 28^2 + sqrt(259)^2
DC=32.3
The angle measuring x° and the angle measuring (3x-70)° are corresponding angles and are this congruent, or
x=3x -70
2x=70 x=35.
so the measure of both of the angles is 35°
