Below is a scatter plot of the data with two linear models, ... in Exercise 3 that represents this man
Answer: No.
Good luck! I hope this is right!
1 radian
because s= r × angle measurement in radian
we have s= arc , r = radian so we got the value
Since triangle ABC is similar to triangle DEF then the ratio of the corresponding sides is constant.
The ratio of the corresponding lengths is referred to as the linear scale factor.
Considering the heights of the two triangles;
L.S.F = 14/6
= 7/3
The ratio in area (A.S.F) is given by (L.S.F)²
Therefore, A.S.F = (7/3)² = 49/9
Thus te ratio of the area of triangle ABC to DEF is 49:9
The value of the expression
