Answer:
42.64°
Step-by-step explanation:
Note: A rhombus has all its sides equal, its opposite angle are equal, its has bigger and smaller diagonal, diagonal bisect the angles and diagonal bisect each other.
From the diagram attached,
sinθ = opposite/adjacent
sinθ = 4/11
θ = sin⁻¹(4/11)
θ = 21.32
Therefore, from the diagram,
The smaller angle of the rhombus = 2θ
The smaller angle of the rhombus = (2×21.32)
The smaller angle of the rhombus = 42.64°
Answer: The equation that can be used to find x, is given by

Step-by-step explanation:
Let the number of degrees he lowered the temperature by each time be 'x'.
Temperature he starts with = 12.2° C
Temperature he stopped with = -14.61° C
According to question, it is said that he lowers the temperature 5 times by the same amount each time.
So, it becomes,

Hence, the equation that can be used to find x, is given by

Answer:
50
Step-by-step explanation:
The ratio of marked fish to caught fish is 4:10, we need to solve for x in 20:x, since 4 * 5 = 20, 10 * 5 = x so x = 50 fish.
