Question

How do i work out the angle

Answer 1

The angle opposite to 304° has measure:-

• 360-304
• 56°

The angle aside 115° has measure

• 180-115
• 65°

Now

Sum of two interiors=Exterior

• x=56+65
• x=121°

Answer 2

x = 121°

Explanation:

the angle at the vertex = 360° - 304° = 56°

the base angle = 180° - 115° = 65°

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

x is an exterior angle of the triangle , then

x = 56° + 65° = 121°
