Give me a minute or two to graph them and then ill let you know :)
Answer:
The diameter of the circle is 24.9 in
Step-by-step explanation:
To solve this exercise we need to use the circumference formula of a circle and clear d:
c = circumference = 78.1 in
d = diameter
π = 3.14
c = π * d
d = c / π
we replace the known values
d = 78.1 in / 3.14
d = 24.8726 in
round to the nearest tenth
d = 24.8726 in = 24.9 in
The diameter of the circle is 24.9 in
Answer:
1. 12/13 and 5/13
2. 5/13 and 12/13
3. The sin of <A and cos of <B are congruent.
Since "Sine" is Opposite/Hypotenuse and Cosine is adjacent hypotenuse...
The opposite of angle A is 12, and the hypotenuse is 12, therefore making 12/13.
The adjacent of angle B is 12, (The adjacent side is the side next to the opposite that is not the hypotenuse) and the hypotenuse is 13, therefore making 12/13. (The hypotenuse never changes no matter how you look at the triangle.)
Sin <A = 12/13
Cos <B= 12/13
