Answer:
one triangle
Step-by-step explanation:
The given angle is opposite the longest given side, so this case is <em>not ambiguous</em>. These numbers define one triangle.
_____
<em>Comment on ambiguity</em>
The <em>law of sines</em> only gives rise to ambiguity (two solutions) only if the given angle is opposite the shorter of the two given sides, <u>and</u> the ratio of side lengths (short/long) is greater than the sine of the given angle.
In the extremely rare case of the side ratio being exactly equal to the sine of the angle opposite the shorter side, the triangle is a right triangle and there is exactly one solution.
Answer:
Step-by-step explanation:
Given
sin x = - 1
x = ( - 1 )
= + 2kπ k ∈ Z
For 2π < x < 4π, then
x =
The correct choice is the final answer.
We want x to be greater than or equal to 4.3. The closed circle tells us that it can be equal to 4.3. The ray to the right tells us that we are looking for numbers larger than 4.3.

Answer:
Hello! answer: 62.8
Step-by-step explanation:
Cirmcumfrence can be found by doing
diameter × pi are diameter is 20 and pi is 3.14
20 × 3.14 = 62.8 therefore the circumference is 62.8 HOPE THAT HELPS!
