Trigonometric functions which are related by having the same value at complementary angles are called cofunctions. Cofunctions of complementary angles are equal.
A. csc 20' = csc(90-70)=sec 70
B. cos 87' = cos (90-3)=sin 3'
C. csc 40' = csc(90-50) =sec50'
D. tan 15' = tan(90-75)= cot 75'
Among all the option c is not correct.
Option C is false.

Step-by-step explanation:
Answer:
T = 91
Step-by-step explanation:
Simplifying
T + -15 = 76
Reorder the terms:
-15 + T = 76
Solving
-15 + T = 76
Solving for variable 'T'.
Move all terms containing T to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + T = 76 + 15
Combine like terms: -15 + 15 = 0
0 + T = 76 + 15
T = 76 + 15
Combine like terms: 76 + 15 = 91
T = 91
Simplifying
T = 91
To get the answer, divide 1456 by 30
1456 / 30 = 48.53
Because there is leftover coins that cant fit a complete page, they would need one more page.
48 + 1 = 49
Kevin and his dad would need 49 pages to put all thr coins in the album.
