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°
Answer:
length = 3 3/4
Step-by-step explanation:
13 = 2(2 3/4) + 2l
13 = 2(11/4) + 2l
13 = 22/4 + 2l
52/4 - 22/4 = 2l
30/4 = 2l
30/4 ÷ 2 = l
30/4 x 1/2 = l
30/8 = l
length = 15/4 or 3 3/4
Answer:
The answer is 0
Step-by-step explanation:
The fraction is already equal to 0 since there is nothing out of -3. Multiplying by any number whether positive or negative, the answer is going to be 0.
A-Infinite. If you distribute the 4 to the 2x+3 you get 8x+12-7=8x+5. This simplifies to 8x+5=8x+5 which means no matter what the value of x is, the two sides of the equation will be equal to each other.
