Answer:

Step-by-step explanation:

All triangles have 180 as the sum of the 3 interior angles.

x + 74 + 55 + 54 = 180            Combine

x + 183 = 180                           Subtract 183 from both sides.

x = 180 - 183                            Combine

x = - 3

You probably have been told that there is no such thing as a minus angle, and that's true. The angle isn't minus. Just x is. The size of the angle is

Angle size = 74 - 3 = 71

Now try adding them together

55 + 54 + 71 = 180 which is what it should come to

6. If m∠COD=8x+13, m∠BOC=3x-10, and m∠BOD=12x-6, find m∠BOD
Ahat [919]

Answer:

Step-by-step explanation:

Given

m∠COD=8x+13,

m∠BOC=3x-10, and

m∠BOD=12x-6

The following addition property is true;

<BOD = <BOC + <COD

Substitute

12x-6 = 3x-10+8x+13

12x-6 = 11x+3

12x-11x = 3+6

x = 9

Get <BOD

<BOD = 12x-6

<BOD = 12(9)-6

<BOD = 108-6

<BOD = 102°
