Answer and explanation:
We know the sum of interior angles in a triangle is 180°.
- 1 : 2 : 3 = 6 (1 + 2 + 3)
- x : y : z = 180 (x, y and z are the unknown angles)
To get from 6 to 180, we multiply by 30. This means we can find the angles by doing:
- 1 × 30 = 30°
- 2 × 30 = 60°
- 3 × 30 = 90°
The triangle must be right-angled because one of the angles is 90°. We know that the shape is a triangle because 30 + 60 + 90 = 180°.
The ratio is 30 : 60 : 90.
Hope this helps!
Let's consider each of the option
5(x-6)
5 times the difference of a number x and 6
This could be written in another way
5(6-x)
Just that one would be a positive difference and the other would be a negative difference..
The last option would have been correct but if we're to consider pedmas.. The last option is suggesting "the difference of 5 times a number and 6" which is not what the question dictates...
The penultimate option is suggesting "6 times the difference between a number and 5"
And the second option is completely astray........
Hope this helped......

Answer:
C. 36 degrees
Step-by-step explanation:
90 + 54 = 144
180 - 144 = 36
you were correct
