Answer:
The height of the ladder above the ground is 25.4306 ft
Step-by-step explanation:
The length of the ladder represents the hypotenuse of the right angle triangle.
The ground distance from the base of the building to the foot of the ladder represents the adjacent side of the right angle triangle.
Therefore, to determine how high up is the top of the ladder from the ground,x which represents the opposite side of the right angle triangle, we would apply trigonometric ratio,
Sin θ = opposite side/hypotenuse
Sin 78 = x/26
x = 26Sin78 = 26 × 0.9781
x = 25.4306 ft
Answer:
58.29cm²
Step-by-step explanation:
The formula for the area of a trapezium is ×(sum of parallel lines)×height
×(7+10.4)×6.7 = ×17.4×6.7
= 58.29cm²
Answer:
68%
Step-by-step explanation:
17/25 decimal form .68
move decimal point 2 places to find percent of .68
Answer:
escalator?
Step-by-step explanation:
An escalator begins at 7.6 feet and increases steadily at 0.2 feet. You could then determine how high the escalator is after so many seconds(x), as well as how long it would take to get to a certian height (y).
