for triangle HLM
180-2x
180-(3x+6)
H
2x=3x-10
x=10°
180-36=144°
36-20=16°
H=2x
H= 180-144-16= 20°
Answer:
176degrees
Step-by-step explanation:
Find the diagram attached. From the diagram;
arcGC = = arc BG
5x + 28 = 9x - 20
5x - 9x = -20 28
-4x = -48
x = -48/-4
x = 12
Get <AB
Since <AB = <BC
<BC = arcGC +arc BG
<AB = arcGC+ arc BG
<AB = 5x + 28 + 9x - 20
<AB = 14x + 8
<AB = 14(12) + 8
<AB = 168 + 8
<AB = 176degrees
Hence the arc AB is 176degrees
