Answer:
I cant tell what u mean but if the angles are equal the answer is 10
Step-by-step explanation:
Based on the calculations, the value of x is equal to 42.5.
Given the following data:
To determine the value of x:
A supplementary angle can be defined as two (2) angles or arc whose sum is equal to 180 degrees.
Mathematically, a supplementary angle is calculated as follows:
[tex]Angle\;2+Angle\;4 =180\\\\3x-5 +x+15=180\\\\4x+10=180\\\\4x=180-10\\\\4x=170\\\\x=\frac{170}{4}[/tex]
x = 42.5.
