Answer:
One
Step-by-step explanation:
9/sin(34) = 6/sinC
sinC = 0.372795269
C = 21.9, 158.1
Since 158.1 + 34 = 192.1 > 180
Only one triangle can be formed with angle 21.9° at C
Given :
Admission price , A = $15 .
Price of each ride , p = $3 .
Number of rides , r = 3 .
To Find :
Total money spend if he goes on 5 rides and for r number of rides .
Solution :
Let , total amount paid is P .
First we find the general equation :


Now , for r = 5 , total price is :

Hence , this is the required solution .
Answer:
C
Step-by-step explanation:
The domain is the set of x-values used by the graph.
Answer:
D E + E F greater-than D F
5 less-than D F less-than 13
Triangle D E F is a scalene triangle
Step-by-step explanation:
we know that
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
we have the triangle EDF
where

<u><em>Applying the triangle inequality theorem</em></u>
1)

2)

so
The length of DF is the interval -----> (5,13)
The triangle DEF is a scalene triangle (the three length sides are different)
therefore
<em>The statements that are true are</em>
D E + E F greater-than D F
5 less-than D F less-than 13
Triangle D E F is a scalene triangle
