Answer:
okay.
the value of x is 35°
and the angle measurement from least to greatest are 35,40 and 105.
Explanation:
40°+3x°+x°=180
40+4x=180
(collect like terms)
4x=180-40
4x=140
(Divide both sides by the coefficient of x)
4x÷4=140÷4
x=35°(35 is the value of x)
then for the three angle measurement from least to greatest we have
180=(40°+3°×35°+1°×35°)
180=40+105+35
180=180°
therefore the angle measures in order from least to greatest are 35,40 and 105...thanks.
