In ΔABC, what is the measure of angle B?
DiKsa [7]
This theorem says that the exterior angle is equal to the sum of its remote interior angles.  In other words, 140 = 2x + x + 2.  140 = 3x + 2 and 138 = 3x.  Therefore, x = 46. Multiply it by 2 to get angle B is 92 degrees.

Crazy boy [7]

Answer:

The  test statistic is  t  = 3.744

Step-by-step explanation:

From the question we are told that

  The population mean is  \mu  =  140

  The  The  level of significance is  \alpha  =  0.05

  The  sample size is  n =  18

   The  null hypothesis is  H_o :  \mu =  140

    The  alternative hypothesis is  H_a  :  \mu > 140

    The sample mean is  \= x  =  155

     The  standard deviation is  \sigma  =  17

Generally the test statistics is mathematically represented as

       t  =  \frac{\= x  - \mu }{ \frac{ \sigma}{ \sqrt{n} } }

substituting values

      t  =  \frac{ 155  - 140 }{ \frac{ 17 }{ \sqrt{18} } }

      t  = 3.744
