How to find area of sector with radius and central angle?

Mathematics

If you have not already, convert the angle into a radius. xπ/180 where x is the angle in degrees. 

The formula for area is A=r²Ф/2 where r is radius and Ф is angle in radians. 

Solve to find the area. 

Hope I helped :)

What is the equation of the line that has a slope of 3 and goes through the point (-3,-5)?
enot [183]

Answer:

y = 3x -4

Step-by-step explanation:

point slope form:

y - y1 = m(x-x1)

y-(-5) = 3(x-(-3))

y+5 = 3x + 9

y = 3x -4

Right triangles abc and dbc with right angle c are given below. If cos(a)=15,ab=12 and cd=2, find the length of bd.
dmitriy555 [2]

see the attached figure to better understand the problem

we have that

cos(A)=\frac{1}{5} \\ AB=12\ units\\ CD=2\ units

Step 1

<u>Find the value of AC</u>

we know that

in the right triangle ABC

cos (A)=(AC/AB)\\AC=AB*cos(A)

substitute the values in the formula

AC=12*(1/5)\\ AC=2.4\ units

Step 2

<u>Find the value of BC</u>

we know that

in the right triangle ABC

Applying the Pythagorean Theorem

AB^{2} =AC^{2}+BC^{2}\\ BC^{2}=AB^{2} -AC^{2}

substitute the values

BC^{2}=12^{2} -2.4^{2}\\BC^{2}= 138.24\\ BC=11.76\ units

Step 3  

<u>Find the value of BD</u>

we know that

in the right triangle BCD

Applying the Pythagorean Theorem

BD^{2} =DC^{2}+BC^{2}

substitute the values  

BD^{2} =2^{2}+11.76^{2}

BD=11.93\ units

therefore

<u>the answer is</u>

the length of BD is 11.93 units
