Answer:
9
Step-by-step explanation:
The ladder is the hypotenuse, the wall is one of the legs. In order to find the other leg you have to do c^2-a^2=b^2. 41^2-40^2 is 81 and the square root of that is 9
-5.6(repeating 6), -√(21), 3&9/10, 5.2
Area of shaded region = area of outer circle - area of inner circle.
288pi = pi * (2x)^2 - pi * 6^2
288 = 4x^2 - 36
4x^2 = 324
x^2 = 81
x = 9 cms Answer
Answer:
<h3>
67°</h3>
Step-by-step explanation:
Given figure is an isosceles trapezoid. Then angles corresponding to equal sides must also be equal. Hence, X = 67°
Theorem: If a quadrilateral ( with one set of parallel sides ) is an isosceles trapezoid, it's legs are congruent.
