Answer:
5 sqrt(3) =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan 30 = x/15
15 tan 30 = x
15 ( sqrt(3)/3) = x
5 sqrt(3) =x
The perimeter of the figure is 50.56 cm.
Solution:
Radius of the quarter of a circle = 8 cm
Perimeter of the quarter circle = 

= 12.56 cm
In figure, one side of the quarter circle is merged with rectangle, so remove one radius from the perimeter of the quarter circle.
Perimeter of the given quarter circle = 12.56 cm – one radius
= 12.56 cm – 8 cm
= 4.56 cm
Perimeter of the rectangle given = (17 – 8) cm + 10 cm + 17 cm + 10 cm
= 9 cm + 10 cm + 17 cm + 10 cm
= 46 cm
Perimeter of the given figure = 4.56 cm + 46 cm
= 50.56 cm
Hence the perimeter of the figure is 50.56 cm.
Answer:
1.75 in
Step-by-step explanation:
Diameter = 3.5 in
Radius = D ÷ 2 = 1.75 in
I hope this helpls
Since r=1, area of circle is pi*r^2, which is just pi (1). Your answer is PI.
Put together they will make a 90 degree angle so 15x+8x -2= 90 combine like terms you get 23x-2=90 +2= 92= 23x now 92/23 is 4 so x= 4
