Question

the area of a right triangular region is 129.5cm if one of the sides containing th rigjt angle is 14.8 cm, find the other one

Answer 1

Area of triangle equals to 1/2*base*height. 
area =129. 5
height=14. 8
other side=x

substitute in the above equation

129.5=1/2*14. 8*x
x=17.5
we got one side
now we have two sides i.e height=14.8 $ base=17.5
Now use the pythogores theorm
hypoteneouse^2=base^2*height^2
Subtitute the value
And you will get hypoteneois which will be other side.

Hope This Helps :)

Answer 2

Area of right triangle is1/2*base*height.height is 14.8 by using this formula answer is 17.5cm
