Question

ABC is a triangle in which A=90degree a circle is inscribed in a triangle if the sidess of the triangle are 8 cm and6 cm find radius of the circle

Answer 1

Answer:

Step-by-step explanation:

Angle A=90°

AB=8cm

Bc=6cm

Ac(hypotenuse)=X

Using Pythagoras theorm we get

Ab^2+bc^2=ac^2

8^2+6^2=ac^2

64+36=ac^2

100=ac^2

Ac=10

Now to calculate the radius of the circle

a=8

b=6

c=10

Using formula

a+b-c/2

8+6-10/2

14-10/2

4/2

2 cm is the radius

NOTE: ABOVE FORMULA CAN BE USED ONLY WHEN TRIANGLE IS RIGHT ANGLE
