Answer:
The cosine of the complementary angle to 38° is 0.62. Answer: d
Explanation:
Complementary Angle
Two angles x and y are complementary if
x+y=90°
The complementary angle of 38° is 90°-38°= 52°
Now use a calculator to find the approximate value of
[tex]\cos 52^\circ \approx 0.61566[/tex]
Rounding to two decimal places:
[tex]\cos 52^\circ \approx 0.62[/tex]
a. Incorrect. The cosine of 52° is not 0.68
b. Incorrect. The cosine of 52° is not -0.16
c. Incorrect. The cosine of 52° is not -0.22
d. Correct. The cosine of 52° is 0.62 to two decimal places.
