Answer 1

Answer:

hey mate here is ur answers....

Step-by-step explanation:

14)In an isosceles triangle two sides are equal.

Here the the base and the perpendicular of the triangle are equal in length.

Area of triangle = 8cm^2

8cm^2 = 1/2 × b × h

Put b & h as X

16 = x^2

X = 4 cm

So, the length of base and perpendicular are 4cm.

H^2 = B^2 + P^2

( H is hypotenuse,B is base & P is perpendicular)

H^2 = 4^4 + 4^2

H^2 = 16 + 16

H = √32

H = 4√2

H = 5.65cm

H = 5.7cm

therefore,the length of hypotheses of the triangle is 5.7 cm....
