Answer:
0.18
Step-by-step explanation:
Alright so these ratios have many different forms but the way I use to remember the trigonometric ratios is:
SOH
CAH
TOA
This means:
Sine --> Opposite/Hypotenuse
Cosine --> Adjacent/Hypotenuse
Tangent --> Oppositie/Adjacent
With that in mind, number 1:
Would be Sine, or C.
Number 2 would be, Cosine, or E.
And number 3 would be Tangent, or B.
Hope that was helpful.
Answer:
Area of the shaded region = 
Step-by-step explanation:
Area of the Shaded region= Area of rectangle - Area of the triangle
Area of the rectangle= Length * breadth
Putting the values in the formula
Area of the rectangle :
Area of the Triangle = 
Base of triangle= 20 inches , Height of the triangle = 10 inches
Area of triangle 
Area of the shade region:
36/12=3 Which give you the enlargement of the smaller triangle to the bigger one.
You work out the missing side by putting it into an equation:
3(x-10)=39
Then solve it.
First expand the brackets:
3x-30=39
The rearrange to get x on its own and that will be your answer:
3x=39+30
3x=69
x=69/3
x=23
