Answer:
x = 9 on APX
Step-by-step explanation:
x = 9
Adjacent angles A and D are supplementary:
(30 +5x)° +(15 +10x)° = 180°
15x +45 = 180 . . . . . collect terms, divide by °
15x = 135 . . . . . . . . . subtract 45
135/15 = x = 9 . . . . . divide by the coefficient of x
The value of x is 9.
DE=11 UNITS
Given AC=CD
And AC=2AB as B is the mid point of AC
Hence 2(3x+4)=11x-17
6x+8=11x-17
11x-6x=17+8
5x=25
x=5
Hence AC=11(5)-17= 55-17=38
AC =CD = 38
CE = 49
Hence DE = CE-CD= 49-38 = 11
