Answer: 8.94 ft
Step-by-step explanation:
The ladder leaning against the perpendicular wall forms a right angled triangle. As per Pythagorus theorem,
a^2 + b^2 = c^2
8^2 + b^2 = 12^2
64 + b^2 = 144
b^2 = 144 - 64 = √80= 8.94 feet
The answer will be B.11 because you divide 285 by 25
The answer:
ABC, ACD and BDC are right triangles that are similar
since the altitude of the hypotenuse of a right triangle divides the triangle into two triangles that are similar to the original triangle and to each other, therefore the diagram shows the right triangle similarity theorem,
this means ABC ~ ACD <span>~ BDC
so the answer is
</span><span>ABC ~ BDC</span>
40x + 120= 400
40x= 280
X=7
