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:
4y-5xz has a degree of 2
Step-by-step explanation:
The degree of an expression the the largest degree of any of its terms.
The degree of a term is the sum of the exponents of the variables in that term.
4
y
=
4
y
1
has a degree of 1
5xz=5x1z1
has a degree of ( 1+1)=2
(5xz)
has a higher degree than
(4y)
Therefore the degree of the expression is the degree of
(5xz) , namely 2
