Question

Use the properties of triangles to find the unknown angles​

Answer 1

Answer:

Both missing angles are 65 degrees.

Step-by-step explanation:

180-50=130, and since 2 lines are congruent, 130/2=180-x. 130/2=65, therefore 180-x=65, so -x=-115, meaning x=115. Since 2 lines are congruent, x=y, so y=115. Now we can find the missing angles to prove it. 180-115=65, and since x=y, both angles add up to 65. The 3 angles on a triangle have to add up to 180 on a Euclidian plane, so we can prove that x and y both equal 115 that way. 65+65+50=180, so x and y equal 115 and the missing angles are both 65 degrees.
