Question

In right angle triangle hypotunse is 13cm base is 7cm less than height find area​

Answer 1

Answer:

Step-by-step explanation:

hypotenuse(c)=13 cm

height(a)= h

base(b) = h-7

by pythagorus theorum : a^2 + b^2 = c^2

13^2 = (h)^2 + (h-7)^2

h= 12cm

base= 12-7 = 5cm

ar(triangle) = 1/2 x base x height = 1/2 * 12 * 5

= 6 x 5

= 30cm^2
