Secd(38) = 1/cosd(38) = 1/sqrt[1-sind^2(38)] because cos^2(x) + sin^2(x) = 1 cos(30) = sqrt(3)/2 = 0.8660 cos(45) = 0.707 so cos(38) can be assumed to some where around 0.8 = 1/0.8 = 1.25
Therefore D is correct answer

Answer from: Quest
13
step-by-step explanation:
169-1=168
168-3=165
165-5=160
160-7=153
153-9=144
144-11=133
133-13=120
120-15=105
105-17=88
88-19=69
69-21=48
48-23=25
25-25=0
since it took 13times to completely subtract it hence its square root is 13
