The second choice is correct. Given that angle 2 and angle 6 are congruent, the largest in each of the corresponding triangles are vertical angles meaning that two known angles are known in each triangle (and they are equal) which means that the last "unknown" (angles 3 and 7) are congruent. The lines DC and AB correspond with these defined, congruent triangles meaning they are parallel.
Multiply 6 by 2 and add 6cm. the radius is half of the diameter so just multiply by two and add the number.
Step-by-step explanation:
Yes it is a function dearest
60 percent because 3/5= 0.6 and multiply by 100 its 60
