Answer:
The height of building is 21 m
Step-by-step explanation:
According to the Pythagorus Theorem
(Hypotenuse)² = (Base)² + (Perpendicular)²
We need to find out the perpendiclar so arranging the equation
(Hypotenuse)² - (Base)² = (Perpendicular)²
Putting the values
(36)² - (29)² = (Perpendicular)²
1296 - 841 = (Perpendicular)²
455 = (Perpendicular)²
Taking Square root on both sides
√455 = √(Perpendicular)²
21.33 = Perpendicular
Rounding off the value is 21 m
Answer:
In short: 29 rounded to the nearest ten is 30.
Step-by-step explanation:
Locate the tens place (2) then look at the digit to the right (9): In this case, the digit to the right (9) is 5 or above. So, we add 1 to the tens place (2).The digit(s) after the (2) are replaced by zeros (or dropped). Thus, we get 30 as the answer.
