Answer:
130 degrees
Step-by-step explanation:
use protractor and measured angles. Hope i helped you.
We have 26 - 18 = 8; 34 - 26 = 8; 42 - 34 = 8; (an arithmetic progression)
We use the formula an = a1 + (n-1)x8 (the explicit formula)
So, an = 18 + (n-1)x8 ;
Then, an = 8n + 10;
Finally, a52 = 8x52 + 10 = 426 (the 52nd term);
Answer:
s = 156.25 square meters
Step-by-step explanation:
s = 2lw + 2lh + 2wh
s = 2(5.5)(3) + 2(3)(7.25) + 2(5.5)(7.25)
s = 33 + 43.5 + 79.75
s = 156.25 square meters
