An isosceles triangle has angle measures 50°, 50°, and 80°. the side across from the 80° angle is 10 inches long. how long are the other sides?

The value of other side is 7.8 inch.

Explanation:

It is given that the isosceles triangle has angle measures 50°, 50°, and 80°. The side across from the 80° angle is 10 inches long.

Let the given length of other equal sides be x.

The side across from the 50° angle is x inches long.

Law of sine,

Therefore, the value of other side is 7.8 inch.

answer: a. 74

step-by-step explanation:

it shows divided evenly, so add the 37+37 = 74

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.
