Answer:
B
Step-by-step explanation:
The formula for finding the relationship between a secant and a tangent is
tangent length ^2 = external segment secant/full length of secant
In this case
60^2 = 48*(x + 48) Expand
3600 = 48*(x + 48) Remove the brackets/
3600 = 48x + 48^2 Expand
3600 = 48x + 2304 Subtract 2304 from both sides
3600 - 2304 = 48x
1296 = 48x Divide both sides by 48
1296 / 48 = x
x = 27
Answer:
40x +18(x -3) = 468
Step-by-step explanation:
If x is collected from each of 40 repeat customers, the amount collected from them is 40x.
If $3 less is collected from each of 18 new subscribers, the amount collected from them is 18(x -3).
The total amount collected is 468, so we have ...
40x +18(x -3) = 468
Answer:-3
Step-by-step explanation:
Part A
The 4 angles of a quadrilateral add to 360. To see why, draw a line from A to C. The quadrilateral is divided into 2 triangles. All triangles have interior angles that add to 180. Since there are 2 such triangles, the total is 2*180 = 360. Write a summation for the 4 angles.
2x + 3x + x + 90 = 360 Combine like terms on the left
6x + 90 = 360 Subtract 90 from both sides.
6x + 90 - 90 = 360 - 90 Collect like terms
6x = 270 Divide both sides by 6
6x/6 = 270/6 Do the division
x = 45
Part B
Since x = 45 then2x = 90
Since <A and <B = 90 And since they are equal interior angles and
both are 90 degrees,the lines are parallel.
