since the entire angle is 90 degrees, set 17x + 13 and 32 - 2x to equal 90
17x + 13 + 32 - 2x = 90
15x + 13 + 32 = 90
15x + 45 = 90
15x = 45
x = 3
to figure out what DBE is, set the x value of 17x + 13 to 3
17(3) + 13
51 + 13
64
to figure out CBE, set the x value for 32 - 2x to 3
32 - 2(3)
32 - 6
26
DBE = 64 degrees
CBE = 26 degrees
hope this helped!!
