Question

An obtuse triangle has angle measurements of 100°, 60°, and 20°. If the longest side of this triangle is 20 feet,
the length of its shortest side, s?

Answer 1

Answer:

20/sin 100=x/s 20

x=(20s 20)/100

x=6.95 feet

The answer is 6.95 feet

Step-by-step explanation:

Answer 2

Answer:

This is the concept of geometry, we are required to calculate for the length of the shortest side. The shortest side is the side opposite to the smallest angle; Therefore using sine rule we shall have:

a/sin A=b/sinB=c/sinC

let a=20 and A=100

b=x and B=20

thus the shortest side will be given by:

20/sin 100=x/sin 20

x=(20sin 20)/100

x=6.95 feet

The answer is 6.95 feet
