Answer:
28
Step-by-step explanation:
63/9=7
7*4=28
we know that
<u>Alternate interior angles</u> are two interior angles which lie on different parallel lines and on opposite sides of a transversal. Alternate interior angles are congruent
see the attached figure with letters to better understand the problem
in this problem
the parallel lines are the lines a and b
the transversal line is the line c
so
the alternate interior angles are the Angle
and Angle 
m∠3=m∠6
therefore
<u>the answer is the option</u>
Angle
and Angle 
Answer:
30 cm
Step-by-step explanation:
Perimeter = (half the circumference) + (twice the radius)
= (1/2)(2·10 cm) + 2(10 cm)
= 10 cm + 20 cm
= 30 cm
