Answer:
Step-by-step explanation:
height of triangle=√(11²-8.6²)=√(11+8.6)(11-8.6)=√(19.6×2.4)
=√(4×4.9×4×0.6)=4√(4.9×0.6)=4√2.94
area of triangle=1/2 bh=1/2×2×8.6×4√2.94
=34.4×√2.94
≈58.984

Answer: E
Step-by-step explanation:
Given:
The base of the given triangle has two part:
Left( left side of the hypotenuse) = 25
Right ( right side of the hypotenuse) = x
The altitude (h) = 60
To find the value of x.
Formula:
By Altitude rule we know that, the altitude of a triangle is mean proportional between the right and left part of the hypotenuse,

Now,
Putting,
left = 25, altitude = 60 and right = x we get,

or,
[ by cross multiplication]
or, 
or, 
Hence,
The value of x is 144.
