Answer:
(c) longest
Step-by-step explanation:
The largest angle is opposite the <em>longest</em> side.
The sum of all has to equal 180 so solve: (x+10)+(3x-5)+x=180
5x+5=180
5x=175
x=35
hope this helps
Answer:
1 = No 2 = Yes 3 = 1.88
Step-by-step explanation:
Answer:
r=25 1) 155
Step-by-step explanation:
first becuase there is a tranversal line we know that 3(x-5) is equal to 2x+10.
Next we just have to solve for x
3(x-5)=2x+10
3x-15=2x+10
x-15=10
x=25
and because it's a transversal line we just have to subtract 25 from 180 to get (1)
180-25=155
Answer:
Expectation of the gain;
E = (2×$17 + 6×$2 - 28×3)/36
E = -$1.06
Step-by-step explanation:
For 2 and 12
Number of possible outcomes = 2
Gain = 20 - 3 = $17
For 7
Number of possible outcomes = 6
Gain = 5-3 = $2
For others
Number of possible outcomes = 36-(2+6) = 28
Gain = -$3
Expectation of the gain;
E = (2×$17 + 6×$2 - 28×3)/36 = -$38/36
E = -$1.06
