From the value found for the x, the angle ABD is 37° and the angle DBC is 58°.
Linear Expression
A linear expression can be represented by a line. The standard form for this equation is: y=ax+b , for example, y=2x+7.
The question gives that the angle ABC is 95°. The angle ABC is composed of the angles ABD and DBC. Thus, you should sum the angles ABD and DBC, for finding x.
2x+23+9x-5=95
11x+18=95
11x=95-18
11x=77
x=7
Like x=7, you can find the angles ABD and DBC
- Angle ABD = 2*7+23=14+23=37°
- Angle DBC = 9*7-5=63-5=58°
