A. Introduction 20 minutes

For today, you will study about angles formed by lines and a transversal. We
will find out how are they related to each other based on their measurements
and by inductive reasoning.

Are you familiar with the hash symbol at the right?
It is being used by online users in creating hashtags for
events and issues. In this way, they can easily search
for their topic or theme.
Try to answer the questions below.

Questions:
1. What geometric figures are used to represent the hash symbol?
2. Are there angles formed? How many are they?
3. Can you see any similarities between or among the angles?

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
