Answer:
3120
Step-by-step explanation:
step 1:multiply 8 with 0 and 7 with 0
step 2:add a 0 in the end and multiply 8 with 4 . you get 32. take 2 and carry over 3. multiply 7 with 4. you get 28 . add 3 you get 31. now add. you get 3120
∠BEC is formed inside a circle by two intersecting chords. If minor arc BD = 94 and minor arc CA = 166, what is the measure of
1 answer:
The complete question is
<span>∠BEC is formed inside a circle by two intersecting chords. If minor arc BD = 94 and minor arc CA = 166, what is the measure of ∠ BEC?
the picture in the attached figure
we know that
The angle formed inside of a circle by two intersecting chords is </span><span>the half-summit of the arcs that comprise it and its opposite.
so
</span>∠BED=(1/2)*[arc AC+arc BD]-----> (1/2)*[166+94]-----> 130°
∠BEC+∠BED=180°-----> by supplementary angles
∠BEC=180-130-----> 50°
<span>
the answer is
</span>∠BEC=50°<span>
