The net can be folded to form a pyramid
The sine of any acute angle is equal to the cosine of its complement. The cosine of any acute angle is equal to the sine of its complement. of any acute angle equals its cofunction of the angle's complement.
A
C
B
Since m∠A = 22º is given, we know m∠B = 68º since there are 180º in the triangle. Since the measures of these acute angles of a right triangle add to 90º, we know these acute angles are complementary. ∠A is the complement of ∠B, and ∠B is the complement of ∠A.
If we write, m∠B = 90º - m∠A (or m∠A = 90º - m∠B ), and we substitute into the original observation, we have:

Answer:
5 times the number
Step-by-step explanation:
We want to find how many ¹/₃ can be made out of ³/₄
The mathematical sum is ³/₄ ÷ ¹/₃
The method for dividing fractions is to flip the second fraction then multiply the two fraction
³/₄ × ³/₁ = ⁹/₄ = 2 ¹/₄ cuts
The greatest number can be cut are 2 pieces with 0.25 meter left over
