Your sister says the horizontal measure from her to the rock wall is 5.5 feet, while the horizontal distance is 13.42 feet. What is the approximate height of her rock wall to the nearest tenth.
Accepted Solution
A:
Answer:12 feetStep-by-step explanation:Given in the question, horizontal distance from sister to rock wall = 5.5 feet diagonal distance from sister to rock wall's peak = 13.42 feet To find the height As we know this figure make a right angle triangle, so we will apply pythagorus theorem hypotenuse² = height² + base²13.42² = height² + 5.5²13.42² - 5.5² = height²149.85 = height²height = √149.85 height = 12.24 feetApproximate height of her rock wall to the nearest tenth = 12 feet
