Can someone please help me with all three of these I’m so desperate to get out this class

m∠U = 80  

m∠B = 44

m∠Q = 93

Step-by-step explanation:

angles of triangles always sum to 180 degrees, so subtract the known angle measures from 180 to get the missing angle measure.  If a right angle is given, it is 90° because by definition all right angles equal 90°

i think is g(1)=-1.

hope that i can

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%
