Answer:</h2><h2>The radius of the circle = 15.92 cm</h2>
Step-by-step explanation:
Given, the central angle of the arc = = 1.256
Length of the arc = 20 cm
Radius of the circle = ?
Radius of the circle = = = 15.92 cm
1)A
2)B
If the dot it is filled it is equal or greater than whatever it is
If the dot is empty it means it is what ever the sign is and it doesn't equal to
Answer:
Step-by-step explanation:
16. m<CAD + m<DAE = - Definition of complementary angles
18. m<CAD + m<DAE = m<CAE = - Substitution property
20. m<CAE = - Definition of perpendicular
21. AE ⊥ AC - AE is tangent to circle C
To prove that AE is tangent to C. Given that CA is the radius of circle C,
Then,
m<CAD + m<DAE =
So that,
AE ⊥ AC
Thus, AE is tangent to C.
