Answer:
am confused
Step-by-step explanation:
81 would be the answer becuss 9 times 9 is 81
False
If the 3 sides form a right triangle then the square of the longest side must equal the sum of the squares of the 2 other sides.
28² = 784
26² + 12² = 674 + 144 = 818 ≠ 784
Thus sides do not form a right triangle.
1st part: you do 180 - 110 = 70
Why you subtract 180 from 110 is linear adds up to 180, so 70 + 110 would get 180 if that makes sense.
2nd part: 180 - 115 = 65
This is similar concept to what I explained with the first part.
3rd part: Triangle sum theorem is 180
4th part: To get angle 7 I believe you just subtract
180 - 70 - 65 = 45
5th part: 7 and 6 I believe are vertical angles and vertical angles are congruent which would make 6 = 7
6 would also = 45
Although I cannot see the options for each of the question(s) choices, I hope this can help you. :)
