Question

Can someone help me this ? Finding an angle measure for a triangle with an extended side

Answer 1

Answer:

x° =121°

Step-by-step explanation:

The inside angles of a triangle together must equal 180°. Therefore, 58° + 63° + n° = 180° if n equals the third angle inside the triangle. So,

180°-(58°+63°)=n°

180° - 121° = n°

59° = n°

Since the outside angle x and 59° must also equal 180°,

180° - 59° = x°

121° = x°

You can also find the exterior angle without finding the interior by adding the two other interior angles together.

58°+63°=x°

121°=x°

Answer 2

The answer is 180 I think soo
