Respuesta :

check the picture below, that's just an example of complementary angles relations in a right-triangle.

the complementary angle of 34° is 90° - 34°, and the

sin(90° - 34°) = cos(34°)
.

so just plug that in your calculator, make sure it's in Degree mode.

Answer:

0.8290

Step-by-step explanation:

If the sum of two angle is 90 degrees then the angles are complimentary angle to each other.

If  x be the complimentary angle of 34° then we have

x + 34° = 90°

x = 90° - 34°

x = 56°

Thus, sine of the complimentary angle of 34° is

sin 56°

= 0.8290
