Question

triangle ABC is an isosceles triangle and BC is the diameter of the circle. what is the area of the triangle.
a 25
b 50
c 75
d 100​

Answer 1

Answer:

Step-by-step explanation:

angle a is 90 degree

so angle b and c are 45 degree each

AB=AC

so

A$B^{2}$+A$C^{2}$=B$C^{2}$

2A$B^{2}$=B$C^{2}$

A$B^{2}$=50

AB=$\sqrt{50}$

Area of triangle=$\frac{1}{2}$x$\sqrt{50}$x$\sqrt{50}$=$\frac{1}{2}$x50=25

Area of triangle =25
