Answer:
65°
Step-by-step explanation:
Short arc AC is the difference between 360° and long arc ABC:
arc AC = 360° -230° = 130°
The inscribed angle ABC that intercepts this short arc will have half the measure of the arc:
∠ABC = 130°/2 = 65°
It means you have to express y in terms of x.
in other words it means you have to re write the equation so that y is in one side and x and some other numbers should be in the other side.
example- y=2x+4 or
y= 5x+6
Step-by-step explanation:
Let x be the number of pages that were skimmed through.
Time taken to skim through = 10 * (x/15) = 2/3 x min.
Time taken to read through = 15 * [(275-x)/10] = 1.5(275-x) min.
We have 2/3 x + 1.5(275-x) = 350.
Therefore 412.5 - 5/6 x = 350 and x = 75.
