i think the answer is 146.8 because two angles in a triangle should always add up to 180 therefore you solve the equation:
180 = 3x + 4 + 2x + 10
combine like terms.
180 = 5x + 14
get rid of the variable (14)
180 -14 = 5x + 14 - 14
166 = 5x
the divide to get x
166/5x = 33.2
33.2 = x
then you’re going to subtract your answer from 180 to get the angle measurement of the third angle, the answer you should get it 146.8
hope this helps!!
