Answer:
x = 35,
Step-by-step explanation:
and the angle measures are 35, 40, 105 degrees
formulate an equation: 180= 40+ 3x+x; hence, 180=40+ 4x; 140= 4x; x= 35. You have to then substitute that in for the value of the angles. 3 times 35 is 105. The rest goes in. Order than from least to greatest don't forget.
yep i found the answer button lol.
