This is a fraction equal to
2 1 ÷ 4 8
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 4
2 1 ÷ 4
4 8 ÷ 4
=
0.5 1
1 8
=
0.5 1
8
= 0.5 1 per 8
Same side angles together form angle with measure 180^{0}. Let x be a measure of smaller angle, then x+20^{0} is measure of bigger angle.
x+x+20^{0}=180^{0}
2x=160^{0}
x=80^{0}.
So measure of smaller angle is 80^{0} and measure of bigger angle is x+20^{0}=80^{0}+20^{0}=100^{0}.
The answer is 3n9 units. So the second one
Answer:
48
Step-by-step explanation:
central angle with arc of <y is 96
so circumference angle 48
