Answer:
[tex]x = 20[/tex]
Step-by-step explanation:
The question is different from the attachment.
The question itself can not be solved without the right attachment.
So, my answer will be based on the attachment
Given
[tex]m_3 = 5x + 10[/tex]
[tex]m_5 = 3x + 10[/tex]
Required
Find x
m3 and m5 are supplementary. The relationship between than can be written as:
[tex]m_3 + m_5 = 180[/tex]
This gives
[tex]5x + 10 + 3x + 10 = 180[/tex]
Collect Like Terms
[tex]5x + 3x = 180 - 10 -10[/tex]
[tex]8x = 160[/tex]
Solve for x
[tex]x = 160/8[/tex]
[tex]x = 20[/tex]
