Step-by-step explanation:
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°

Hello!
When you use sum you add
-2.1x + 3.7 + 5 + 4.9x
Now you add the variables and the constants
-2.1x + 4.9x = 2.8x
3.7 + 5 = 8.7
Combine the two
2.8x + 8.7
The answer is 2.8x + 8.7
Hope this helps!
