Answer:
Step-by-step explanation:
2x² +21x-61 = (x+7)²
expand
2x² + 21x - 61 = x² + 14x +49
move everything to one side
x² + 7x - 12 = 0
use quadratic formula
plug in the values
solve

Step-by-step explanation:
Pretty Tall.
Tan(72) = opposite / adjacent
The opposite is the height of the building
The adjacent = 100
Tan 72 = 3.077
Tan (72) = opposite / 100
3.077 = opposite / 100 Multiply by 100
3.077 * 100 = opposite
opposite = 307.7
opposite rounded = 308
