Explanation:
"the sum of the angles in a triangle "=180^@
"add the 3 given angles and equate to 180"
x+4+x+2x=180
rArr4x+4=180
"subtract 4 from both sides"
4xcancel(+4)cancel(-4)=180-4
rArr4x=176
"divide both sides by 4"
(cancel(4) x)/cancel(4)=176/4
rArrx=44
"the 3 angles in the triangle are therefore"
x=44^@,x+4=44+4=48^@,2x=2xx44=88^@
"note that "44+48+88=180^@
