The lenth of the hypotenuse of an isoscles right triangle is 30meters. find the area of the triangle. round to the nearest tenth, if necessay.
i made the picture
then i did:
a^2 + b^2 = c^2
? = ? = 30^2
sqrt a^2 + b^2 = sqrt900
so then
sqrta+b = 30
2x = 30
x = 15
so a and b = 15
then offcourse u have to find the area....
1/2 bh
1/2 (15)(15)
1/2 (225)
112 1/2 so this is what i got as my answer.
