Step-by-step explanation
When dividing a fraction by a fraction it is the same as multiply the inverse of the bottom fraction, so 5/9 times 9/7 so the 9's cancel and your left with 5/7
Answer:
The radius of this circle is
and the central angle of the sector is
.
Step-by-step explanation:
Consider the provided information.
If a conical paper funnel is made out of a sector of circle then the radius of the sector becomes the slant height of the cone, and the length of the curved part of the sector becomes the circumference of the base of the cone.
First find the slant height: 



Thus, the radius of the sector is
which is same as the slant height of the cone.
Now, the circumference of the base of the cone is same as the length of the curved part.


The length of the curved part = 



Hence, the radius of this circle is
and the central angle of the sector is
.
Answer:
∠GAC ≅ ∠HFD by the Property of Congruence.
Step-by-step explanation:
I'm going to be honest the question is a little confusing cause of the beginning, but if you're looking for which angles are actually congruent it's ∠GAC ≅ ∠HFD
