3x/10= 1290
Mutiply by 10 for both sides
3x/10*10= 1290*10
Cross out 10 and 10 , divide by 10 and then becomes 3x
3x=12900
divide by 3 for both sides
3x/3= 12900/3
Cross out 3 and 3 , divide by 3 and then becomes x
x= 4300
Answer: x= 4300
Answer:
17.907082 unit
Step-by-step explanation:
According to the Question,
Given, A circle with centre F, ∠EFG=54 and EF=19 .
length of arc EG = Radius(EF) × ∠EFG(in Radian)
- We Know, 1 degree = 0.0174533 Radian
- 54 degree = 0.942478 Radian
length of arc EG = 19 x 0.942478 ⇔ 17.907082 unit
