An isosceles triangle has angle measures 55°, 55°, and 70°. the side across from the 80° angle is 10 inches long. how long are the other sides? a. 8.72 inches b. 11.47 inches c. 10 inches d. 8.19 inches

Measure of three angles of Isosceles Triangle are ,55°, 55°, and 70°.

Length of side across 80° angle = 10 inches

We will use Sine Rule Here, which states that

Length of other sides = 8.41 inches

Option D: 8.19 inches

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
