Question

Help me with this question thingy plas

Answer 1

x = -3

Explanation:

55+54+x+74=180

109+x+74=180

183 + x = 180

x = -3

Answer 2

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
