Answer:
115
Step-by-step explanation:
angle DEF is an inscribed angle and arc DF is the arc it intercepts
if you didn't know an inscribed angle is equal to half the measure of the arc it intercepts
Hence angle DEF = 1/2 of arc DF
If arc DF = 230 then angle DEF = half of 230 or 230/2
230/2=115
Hence angle DEF = 115
The price of ticket last year is $ 1231.65
<em><u>Solution:</u></em>
Given that,
This year, Sophia paid $1,071 for season tickets to her favorite baseball team , which is 15% cheaper than last year
To find: Price of season ticket last year
Let the price of season ticket last year be "x"
Therefore, according to question
Price of ticket this year is 15 % cheaper than price of ticket last year
1071 = price of ticket last year - 15 % of 1071
1071 = x - 15 % of 1071
Solve the above expression for "x"

Thus price of ticket last year is $ 1231.65
Answer:
Step-by-step explanation:
Use similar triangles and proportions to solve:
and cross multiply:
4(6 + x) = 60 and
24 + 4x = 60 and
4x = 36 so
x = 9
