Work through the problem step-by-step. Step 1: When the circle is cut in half, ( 1 )/ ( 2 ) of the circle is left. Step 2: When that ( 1 )/ ( 2 ) is cut into 4 parts, ( 1 )/ ( 4 ) * ( 1 )/ ( 2 ) = ( 1 )/ ( 8 ) o
1. Geometry Setup: We have a triangle ABC where B is at the origin (0,0), C lies on the positive x-axis at (e,0), and A is above the x-axis at (x,y). Point D is on the x-axis between B and C. Triangle ADC is an internal triangle within ABC, with angles ∠DAC = 60...
To solve the problem regarding the circumcircle and incircle of a right-angled triangle ABC, we will follow these steps: Step 1: Understand the properties of the triangle Given that triangle ABC is a right-angled triangle, we know that the circumradiusRcan be calculated using the formula: ...
Since OP is a radius that intersects the chord QR, it will bisect QR at point S and will be perpendicular to QR. Thus, we can denote:- OS=x- SR=y Step 4: Apply the Pythagorean TheoremIn triangle PSR:PR2=PS2+SR2Where:- PR=12 cm (length of the chord)- PS=OP−OS=10−x So...

1. The Problem: The “Fundamental Lemma” (FL) What is it?A technical hurdle in the Langlands Program (a grand math theory connecting number theory and geometry). Think of it like akey missing puzzle piece: Without proving FL, many big results in math couldn’t move forward. ...
To solve the problem, we need to find the distance d from the vertex A of an equilateral triangle ABC inscribed in a circle of radius 20√3 cm to its centroid G. 1. Understand the Circumradius: The circumradius R of an equilateral triangle is given as R=20√3 cm. The formula for ...
Step 5: Calculate the area of the circle segment in the first quadrantThe area of the part of the circle that lies in the first quadrant is given by: Area in first quadrant=Area of sector−Area of triangle Substituting the values we found: Area in first quadrant=π2−2 Final Answer...
