Answer:
The relationships, properties, and theorems will be easier to understand when ... Just like you don't want to do a geometry problem without all the given ... In case you want to get a head start… here are arguably some of the most important theorems for triangles: ... In the figure below, both congruent angles have one arch.
Step-by-step explanation:
Answer:
16. No
18. Yes
20. Yes
Step-by-step explanation:
Because there is a right angle at at least one corner of the triangle.
Suppose two quantities = x, y
And you need to y as a unity.
So, you have to divide both the numbers by y, and you will get your answer...easily
Answer:
3 cm
Step-by-step explanation:
So the area of the total circle is:
If you remove the outer band you have the area of the inner circle
This means that the inner circle had an area of
area = pi * r^2
9 pi = pi * r^2
r =
So the radius of the inner circle is 3.
Answer:
Step-by-step explanation:
The measure of the entire area swept out by the minute hand is
A = πr², which in this particular case is:
A = π(4.7 cm)² = 22.09π cm²
The sector in question has the area (25/60)(22.09π cm²), or 9.204π cm², or 28.92 cm² approximately.
