Engineers designed a metal support that forms a 65° 65 degreesangle with a dam. Find the measure of the angle's supplement.

x+65°x+65°−x==180°−=

180°

x=115°x=115°

To find the measure of the angle's supplement, we need to subtract the given angle (65°) from 180°.

180° - 65° = 115°

Therefore, the measure of the angle's supplement is 115°.
