Answer: A. 0 <------
Step-by-step explanation:
Law of Sines
sinA / a = sinB / b
sin31 / 10 = sinB/ 40
sinB = 40sin31 / 10
sinB = 2.060152299640217
Since 1 is the maximum for sin
the triangle does not exist
A. 0 <------
Zero pairs can be (+1)+(-1)=0.
Answer: A 30-60-90 triangle is a special right triangle (a right triangle being any triangle that contains a 90 degree angle) that always has degree angles of 30 degrees, 60 degrees, and 90 degrees. Because it is a special triangle, it also has side length values which are always in a consistent relationship with one another.
The basic 30-60-90 triangle ratio is:
Side opposite the 30° angle: x
Side opposite the 60° angle: x*√3
Side opposite the 90° angle: 2x
