Given,
2pen and 5 pencil cost 120
3pen and 2 pencil cost 114
let pen be X and pencil be Y
2x+5y=120 ......(1)
3x+2y=114 ........(2)
solving 1 and 2 , we can get the value of pen and pencil.
x=30
Y=12
Answer:
m<1 = 121°
m<2 = 59°
Step-by-step explanation:
If m<1 is the supplement of m<2 and the measure of each angle is given:
m<1=2x+65
m<2=3x-25
Find m<1:
When two angles are supplement of each other, there sum is equal to 180°
i.e m<1 + m<2 = 180°
Putting values and finding angle 1

So, we get x=28
Now finding m<1 by putting x=28

Now, finding m<2 by putting x=28

So, we get:
m<1 = 121°
m<2 = 59°
