Given:
m(ar AB) = 116°
To find:
1. The measure of arc BEA.
2. The measure of ∠CAB
3. The measure of ∠BAD
Solution:
1. The measure of arc of full circle is 360°.
m(ar AB) + m(ar BEA) = 360°
116° + m(ar BEA) = 360°
Subtract 116° from both sides.
m(ar BEA) = 244°
2. Using the tangent-chord angle theorem:
⇒ m∠CAB = 58°
3. Using the tangent-chord angle theorem:
⇒ m∠BAD = 122°
Using the fact that it is supplementary to ∠CAB.
⇒ m∠CAB + m∠BAD = 180°
⇒ 58° + m∠BAD = 180°
Subtract 58° from both sides.
⇒ m∠BAD = 122°
The statement below is sometimes true. An example of this is with 1 and 2. Their lowest common multiple is 2 and 1 times 2 is 2. So, that's correct. Another example of this is with 2 and 4. Their lowest common multiple is four and 2 times 4 is 2 so that's not always right.
Answer:
Use the given length of a different side of the triangle to determine the value of x if x is the length of one side. Every side of an equilateral triangle is the same. Multiply the length of one side of the triangle by three to find the value of x, if x is the triangle's perimeter.

if she paid $13 for
she actually paid
so 13÷10=1.3$ per kg
