Answer:
Step-by-step explanation:
If half a number is 120, then the number before it was cut in half is 240. What we need to find now is 14% of 240.
"14% of 240 is what" in an algebraic equation looks like this:
.14(240) = x and
x = 33.6
X + 388 = 388 + 152
x + 388 = 540
-388 -388
------------------------
x=152
Answer:
angles
1x
3x
5x
1x +3x +5x = 180 (ASP)
9x = 180
x= 180÷9
x= 20
1x= 20
3x= 60
5x=100
angles are 20°, 60°, 100°
