Answer:
C
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
(7x - 40) is an exterior angle of the triangle, then
7x - 40 = 3x + 3x - 20
7x - 40 = 6x - 20 ( subtract 6x from both sides )
x - 40 = - 20 ( add 40 to both sides )
x = 20 → C
9 + 9 + 3 + 7 + 4 + 6 + 4 + 5 + 7 + 3 + 6 = 63
Hi,
Based on this, I am not sure how close they want the number to be “8” but here is the work:
1.) 9
2.) 7
3.) 7
4.) 8
5.) 8
Most likely it is 4 and 5 but it could be others if they think it’s close to 8 thank you!
