Step-by-step explanation:

J = 2b

M = J + 7

M = 21

J = 21 - 7

J = 14

B = 7

<em>Equation:</em>

If M is J+7, so then J = 21-7. J is 2*b, so 2*b = 21-7. Then you subtract and divide.

Can someone help me this ? Finding an angle measure for a triangle with an extended side
Sedaia [141]

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°
