Answer:
angle 2=120°
angle 1=60
Step-by-step explanation:
70+50=120
or
180-(70+50)=60
angles on a straight line add up to 180°
180-60=120
The singles digit is 0.
The 2 is the tens digit and the 4 is the hundreds digit.
1) let both have x ,
so putting in eqn ;
4x+0.50 = 9x-3
5x=2.50
x=0.50
therefore both have 50 p in the beginning !!
2) let the number be x
so in eqn;
(x+18)/2=5x
x+18=10x
9x=18
x=2
so the number must be 2 !!
if you have still any problem, comment !!
