If 21 is added to (+ 21) a number (x) the result (=) is 40 less than (- 40) twice the number (2x)
x + 21 = 2x - 40 Add 40 to both sides
x + 61 = 2x Subtract x from both sides
61 = x Switch the sides to make it easier to read
x = 61
Answer:
the answer is A. because a 1/2 inch is 2 feet there is about 2 and 1/2 of an inch so if you add that, that will be 9 feet
Step-by-step explanation:
Answer:

Step-by-step explanation:
because when you multiply 3x3 (the base) times 18(the height) you get= 162
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°
