Question

Directions - create a triangle angle sum equation then solve for x:





Triangle angle sum equation =


x =
degrees

Answer 1

Answer:

x = 86°

Step-by-step explanation:

x + 37° + 57° = 180° sum of angles in a triangle

x + 94° = 180°

x = 180° - 94°

x = 86°

Answer 2

Answer:

x = 86°

Step-by-step explanation:

The sum of the 3 angles in a triangle is 180°

sum the 3 angles, equate to 180°

x + 57° + 37° = 180° ← angle sum equation

x + 94° = 180° ( subtract 94° from both sides )

x = 86°
