Answer:

Step-by-step explanation:

Length of fence = Perimeter of triangle

                          = 10 + 20 + 15

Length of the fence = 45 m

Cost of fencing per meter = Rs. 25

Cost of fencing 45 m = 25 * 45

                                  = Rs. 1125

You play a game that involves spinning the money wheel shown. you spin the wheel twice find the probability that you get more th
olga2289 [7]
There are 24 segments on the wheel in total. 1 segment is the $500 and 2 are the bankruptcy spaces. You would then multiply the two fractions 1/24 and 2/24 (the chances of getting each result) to get the answer. 1•2=2 and 24•24=576 making the fraction 2/576. Then you would simplify by dividing both sides by 2 which equals the final answer 1/288.

2. Determine whether segment AB is tangent to the given circle
Gemiola [76]

Answer:

no

Step-by-step explanation:

13² should be equal to 4² + 12² for that

checking, we get that 169 is not equal to 16+144= 160

so it's not right angle

to be tangent, it should be right angle
