Answer:

x = 10

y = 20

Step-by-step explanation:

\tan \: 30 \degree =  \frac{x}{10 \sqrt{3} }  \\  \\  \frac{1}{ \sqrt{3} } =  \frac{x}{10 \sqrt{3} }  \\  \\ \sqrt{3} x = 10 \sqrt{3}  \\  \\ x =  \frac{10 \sqrt{3} }{ \sqrt{3} }  \\  \\ x = 10 \\  \\  \cos 30 \degree =  \frac{10 \sqrt{3} }{y}  \\  \\  \frac{ \sqrt{3} }{2}  =  \frac{10 \sqrt{3} }{y}  \\  \\ y =  10 \sqrt{3}  \times  \frac{2}{ \sqrt{3} }  \\  \\ y = 10 \times 2 \\  \\ y = 20

kakasveta [241]

Answer

A = 30.25pi. PLS GIVE BRAINLIEST

Step-by-step explanation:

so if circumference is 11, and formula for circumference is 2pi*r, we can work backwards to find the radius.

Radius: 11pi/2 = 5.5pi = 5.5 is radius

Area = pi * r^2

so Area = pi*5.5^2

so A = 30.25pi left in terms of pi

When it says f(4) that means x=4

So you then just fill in all the x’s with 4’s and solve as normal

Find the are of each figure
Umnica [9.8K]

Answer:

I think the figure of N and E of 48in is 2304. The figure of I and E and N and A of 32in is 1024. The figure of L and I and L and A is 144.

Step-by-step explanation:

To find the area, you have to multiply of each side in each figure. For example, Figure A and B and C and D of 16in is 16 × 16 which is 256.

A = Area

a = Side

A = 2304, A = a^2 = 48^2 = 2304.

A = 1024, A = a^2 = 32^2 = 1024.

A = 144, A = a^2 = 12^2 = 144.

I hope this answers your question!
