Answer: 8x^2° + 52x° + 27°
Using the knowledge i know i think this is the right answer
Have a great day :)
X and Z equal 72
Y equals 108.
This is because y and 108° are vertex angles meaning they are both equal to each other. X is 72 because it’s form a supplementary angle with 108°. So what I did to find x is I subtracted 108 from 180 to get 72°. Then I know x and z are vertex angles meaning that z is also equal to 72°
78 is the significant figure because in maths 0's are not considered significant. Read more into significant figures to help you out.
