Tell whether the angles are complementary or supplementary. Then find the value of x.

the angles are complementary because they add up to 90° because of the red square. x=20

Step-by-step explanation:

4x-5+15=90

4x+10=90 subtract 10 from each side

then you get left with 4x=80

divide 4 from each side then you get left with x=20 and to check just substitute  20 where x is so 4(20)-5= 80-5=75 +15=90.

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%
