How many triangles exist that fit the following criteria?B=100°𝐵=100°, b=6𝑏=6, a=7

The given question is about solving a triangle using the Law of Sines. The Law of Sines states that the ratio of the length of a side of a triangle to the sine of its opposite angle is the same for all three sides and angles.

Here, we are given: Angle B = 100° Side b (opposite angle B) = 6 Side a = 7

We are asked to find how many triangles exist with these conditions.

Step 1: Use the Law of Sines to find Angle A

sin(A) / a = sin(B) / b

Substitute the given values:

sin(A) / 7 = sin(100°) / 6

Solve for sin(A):

sin(A) = (7 * sin(100°)) / 6

Calculate the value:

sin(A) ≈ 1.015

Step 2: Determine the number of possible triangles

Since the sine of an angle cannot be greater than 1, there are no possible triangles that can be formed with the given conditions. Therefore, the answer is 0.
