Find the missing angle and classify the triangle below.

Hello! 60 and the triangle is a Equilateral because each measure is the same HOPE THAT HELPS!

The missing angle is 60 degrees, the triangle is equilateral.

Step-by-step explanation:

A fact about all triangles is that their interior angles (the angles on the inside) add up to 180 degrees. Due to two other angles being already known, you can use math to find the third angle.

180 - 60 - 60 = 60

Since all of the angles are 60 degrees, they are all equal. With this, it can be found that this triangle is an equilateral triangle since all of the angles are equal, and therefore all of the side lengths are equal.

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
