Step-by-step explanation:
The secant- secant angle PRS is half the measure of the difference of the intercepted arcs, that is
(PD - QS) = 50 ( multiply both sides by 2 )
PD - QS = 100, that is
12x + 8 - (4x + 4) = 100
12x + 8 - 4x - 4 = 100
8x + 4 = 100 ( subtract 4 from both sides )
8x = 96 ( divide both sides by 8 )
x = 12
Thus
arc PD = 12(12) + 8 = 144 + 8 = 152°
arc QS = 4(12) + 4 = 48 + 4 = 52°
Example:
You owe someone $45.75 which is -45.75. You are able to pay that person the $45.75 which is positive and equivalent to the amount of money you owe. Add them together and you will get 0, meaning you don't owe them any money anymore.
Move k to the other side to isolate d.
So we will get 3d = 8c - 8d - k
Now divide both sides by 3 to isolate d.
So d = 8/3c - 8/3d - k/3
6:1 , basically asking the ratio of one to the other. Understand?
Answer:
equation involves an equal sign, ' = '
while expression does not have an equal sign.
for example:
an equation is 5x² × 3 = y
an expression is 2xy + 3
