Answer:
The expression is
.
Step-by-step explanation:
Given:
The number of stamps in Kelly's stamp collection is 10 less than half the number of stamps in Marks collection.
Let m represent the number of stamps in marks collection.
Now, to write an expression show the number of stamps in Kelly's collection.
Let
represent the number of stamps in Marks collection.
And the number of stamps collection of Kellys be 
Now, to write an expression:
According to question:


Therefore, the expression is
.
Answer:
θ ≈ 40°
Step-by-step explanation:
Since, sinθ = 
cosθ = 
tanθ = 
In the picture attached,
Measures of adjacent side and opposite side of the triangle have been given. Therefore, tangent rule will be applied in the given triangle.
tanθ = 
θ = 
θ = 39.56
θ ≈ 40°
Answer:
