2. ### What is the area of triangle ABP?

Area of triangle = 0.5 (base)(height) base = AB = 2 height = P to center of AB = FB Using Pythagoras's Theorem, height = √ [(2^2) + (2^2)] height = √8 height = 2√2 Area of triangle = 0.5 (2) (2√2) Area of triangle = 2√2...

8. ### 1-Center(-1,3) and tangent to the line y=22-Center(4,-2) and tangent to the line x=1?

every cicle could be drawn by means of center and radius, so here we should find the radius, Center(-1,3) and tangent to the line y=22, means that the radius is 22-3=19 so (x+1)^2+(y-3)^2=19^2 Center(4,-2) and tangent to the line x=1, means that the radius is 4-1=3 so (x...
