lect all that apply. A) cos(x) b) cos(x - 45°) c) cos(45° - x) d) cos (60° - x ) e) cos(90° - x)
EXPLAIN!!!!
1 answer:
Answer:
e) cos(90° - x)
Step-by-step explanation:
we know that
If two angles are complementary, the cofunction identities state that the sine of one equals the cosine of the other and vice versa
The complementary angle of angle x is equal to (90-x) degrees

Answer:
x = 11
Step-by-step explanation:
sides are proportional so you can set up a proportional and cross-multiply:
JL is to PQ as LK is to QR
x/22 = 8/16
x/22 = 1/2
2x = 22
x = 11
