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:
3.75 or 3 3/4
Step-by-step explanation:
The answer is none of those because you find the median of 51 which is Q2 then the lower median is 34.5 and the upper median is 73.4 then you subtract 73.5-34.5=39
3 slices are left because a quarter of the 8 is 2 so there is 6 left than 6-3=3 so 3 slices are left
