Answer:
Using the calculator angle whose cos is 0.9511 is 18 degrees
Sine of the complementary angle = 0.9511 also
Step-by-step explanation:
The sine of the complementary angle( which is 90-18 = 72 degrees) is same value 0.9511
Answer: 18 degrees and 0.9511
Step-by-step explanation:
18°; 0.9511
Cos-1(0.9511) = 18°
The complement of 18° is 72°. The sine of 72° is the cos of 18°, which is 0.9511.
