Question

Use the diagram below to find xx = 34x = 32x = 30x = 28

Answer 1

use the property, sum of the angles in the triangle is 180 degrees.

Thus, add all the angles,

we get,

`\begin{gathered} x+\mleft(2x+5\mright)+\mleft(3x+7\mright)=180 \\ x+2x+5+3x+7=180 \\ x+2x+3x+5+7=180 \\ 6x+5+7=180 \\ 6x+12=180 \\ 6x=168 \\ (6x)/(6)=(168)/(6) \\ x=28 \end{gathered}`

Hence the value of x= 28
