What is the measurement of angle BEC?

I think its -120 but am not sure so sorry if its wrong

Step-by-step explanation:

what makes these tough is that you have to remember that the total of the angle is known,  you know it to be 180 ° , so since you know the total just set all the part equal to that

180 = 4x + 6x-20 + 5x - 10

now you can slove for x with your mad algebra skilz  :) if you don't have those yet. it's okay.. most people don't  :D  Super hero's and math whizzes only, seem to have those.  :D

180 = 15x -30

210 = 15x

14 = x  

now that we know what x is , plug it into the angle BCE

BCE = 6(14) -20

BCE = 84 -20

BCE = 64 °

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
