From the given information, we get the value of ABC = 120°.
<h3>How to estimate the value of ABC?</h3>
Given: In the figure, O exists the center of the circle and OABC exists as a parallelogram.
Now, the radius of the circle exists
OA = OB = OC
Opposite sides of a parallelogram are equal
AB = OC and OA = BC
In ∆OAB,
OA = OB = AB and,
In ∆OCB,
OC = OB = BC
Therefore, ∆OAB and ∆OCB exist in equilateral triangles.
All angles of an equilateral triangle are equivalent to 60°.
Hence, ∠ABC = ∠OBA + ∠OBC
∠ABC = 60° + 60°
∠ABC = 120°
Therefore, the value of ∠ABC = 120°.

Step-by-step explanation:
Rewrite the expression using only positive exponents. Then, evaluate the expression. 3^{-2}
Answer:3/4
Step-by-step explanation: The probability of spinning a 5 is 1/8, and the probability of spinning an 8 is 1/8, so the probability of spinning either one is 2/8. Therefore, the probability of NOT spinning a 5 or an 8 is 8/8 -2/8 or 6/8 which is the same as 3/4
Answer:
-3/5 = -0.6
-5/8 = -0.625
Step-by-step explanation:
I most definitely did not use a calculator.
Step-by-step explanation:
Find angle W first:
37 + 93 + W = 180 ---> W = 50°
Use sine law to find the length w:
w/(sin 50) = 31/(sin 37)
w = 31(sin 50/sin 37)
= 39.5
