Answer:
(√2)/2; (√2)/2; 1; √2
Step-by-step explanation:
sin A = cos A
1. sin A
sin A/cos A = tan A = 1
A = arctan 1 = 45°
sin A = sin(45°) = (√2)/2
2. cos A
cos A = sin A = (√2)/2
3. cot A
tan A = 1
cot A = 1/tan A = 1/1 = 1
4. sec A
sec A = 1/cos A = 1 ÷ (√2/2) =1 × 2/√2 = √2
5/13 I believe since you add how many games won and lost and you get 13 and since you want to know how many games lost as a fraction it would be 5/13
I think it would be B but I’m not sure for number 7
The enlarged flower bed is a rectangle and its area is x^2+9x+14 m²
So before its enlargement by 14 m², the area of the rectangle = x^2+9x
As you know, the area of rectangle is equal length times width
so area = x^2+9x
factors:
x^2+9x = x (x + 9)
So the dimensions are x and (x + 9)
Hope it helps.
