C = 2πr
141.3 = 2(3.14)r
141.3 = 6.28r
22.5 = r
Answer:
34 points
Step-by-step explanation:
88 minus 54 equals 34.
90
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
If a and b are parallel lines
then
m∠1=m∠4 --------> by alternate exterior angles
m∠3+m∠4=
--------> by supplementary angles
so
m∠3+m∠1=
therefore
<u>the answer is the option</u>
m∠1 = 110° and m∠3 = 70°
