Area of a triangle = 1/2 x base x height
Area = 1/2 x 8.7 x 8.6
Area = 37.41 square feet
Answer:
22.9 ft
Step-by-step explanation:
the height of the wall that reached by the ladder = √ (25²-10²)
=√(625-100)
=√525
= 22.9 ft
The first one is 63.9 and the second should be 116.1
68 because it is a perpendicular bisector we can assume that the angles full length is 90 degrees meaning you can just do 90-22=68
