<PRE><B>Question 898449</B>
If angleABD and angleBDC are complementary then how do I find the measurements if angle ABD is 5x and angle BDC is 17x-18 .
-----
Equation:
The sum of the angles is 180.
5x + 17x-18 = 180 degrees
----
22x = 198
x = 9
---
ABD = 5x = 5*9 = 45 degrees
BDC = 17x-18 = 17*9-18 = 135 degrees
------------
Cheers,
Stan H.
