Step-by-step explanation:
Kindly find attached the solution.
We are given a circle with center O.
We can see that we have a radius OB of given circle.
OC and OE are another two radii.
EC is a diameter of the circle.
<em>Diameter is the segment that cut the circle at two points and passes through center.</em>
AB is a tangent of the given circle.
<em>A tangent is a segment that cut a circle at one point only.</em>
But the chord is GD.
<em>A chord of a circle is the segment that cut a circle at two points.</em>
<h3>Therefore, a chord in circle O is GD.</h3><h3 />
Plug the points in and find that this is indeed the right answer. Are you in college math? Because I am, and my dashboard looks just like that!
the figure is an equilateral triangle, which all angles are 60 degrees
angle 3 divides a 60 degree angle in half so angle 3 = 30 degrees
the base is a right triangle which is 90 degrees
90+30 = 120
180-120 = 60
Angle 2 is 60 degrees
