The answer is 24 : 12 x 1 / cos60 = 24
In 2000, 7689 weekly papers = 94% of number of weekly papers in 1960
Let weekly papers in 1960 be x.
7689 = 94% of x
7689 = (94/100)*x
7689 * 100/94 = x
8179.787 ≈ x
x ≈ 8179.787
Number of weekly newspapers in 1960 rounded to the nearest whole number = 8180
Answer:
-5.1
Step-by-step explanation:
Subtract 5.1 from both sides.
Larger number = X
Smaller number = 1/2X
X + 1/2X = 60
Simplify:
1 1/2x = 60
Divide both sides by 1 1/2:
x = 40
The numbers are 20 and 40
Both angles ABO and ADO are right angles because ABP and ADQ are tangent to circle O. The interior angles of a quadrilateral add up to 360 degrees, so the measure of angle BOD (and measure of minor arc BD, denoted ) is
This also means the measure of the central angle BOD that subtends major arc BCD (also the measure of the major arc BCD is)
The inscribed angle theorem says that the measure of angle BOD is twice the measure of angle BCD, so
The interior angles of quadrilateral BCDO have sum
Simplifying this equation will give you .
