Answer:
The ratio of the slant heights of the two cones will also be n : m.
Step-by-step explanation:
See the attached diagram.
If we take the vertical sections along any diameter of the base circle of the cones A and B then the triangular sections as we get will be similar.
Now, ratio of the base of the triangles A and B i.e. the ratio of the diameters of the cones A and B will be 2n : 2m = n : m and this will be the same as the ratios of other two sides of the triangles A and B.
Therefore, the ratio of the slant heights of the two cones will also be n : m. (Answer)
Answer:

Step-by-step explanation:
The given expresion is

We multiply through by 8 to get:

We cancel out to obtain:

We simplify to obtain:

THE ANSWER IS 5 since the decimals are out of place
Answer:
Answer to fourth part is :
Angle ABC= Angle DBC
So for fifth part reason answer is ASA congruency.
Step-by-step explanation:
Here we are given that CB bisects angle ABD and angle ACD.
So we have ,
Angle ABC= Angle DBC
Answer to fourth part is :
Angle ABC= Angle DBC
Now here we have two angles and one side equal in two triangles.
So we can say that ASA congruency fits in the best here.
So for fifth part reason answer is ASA congruency.
