Find the value of X 101 92 54 87

I believe it would be 92 degrees. The 3 angles add up to 268 degrees, and all of the outside angles should add to 360 degrees. So 360-268=92.

I need to find the missing angle measures.
scoray [572]

Answer:

step 1. b = 102° (vertical angles)

step 2. one complete revolution equals 360°

step 3. a + b + c + 102 = 360

step 4. a + 102 + c + 102 = 360

step 5. a + c = 156°

step 6. 2a = 156 (vertical angles are equal)

step 7. a = 78°, c = 78°.

How can I simplify this expression
kodGreya [7K]
Usually, "simplify" means to remove any common factors and express the sum as a single fraction, often in multiplie-out form.

If you factor what you've got, you will write it as
\dfrac{(m+2)(m-2)}{(m+1)}+\dfrac{(m+2)}{(m+1)^2}=\dfrac{m+2}{m+1}\cdot\left((m-2)+\dfrac{1}{m+1}\right)\\\\=\dfrac{m+2}{m+1}\cdot\dfrac{(m-2)(m+1)+1}{m+1}\\\\=\dfrac{(m+2)(m^2-m-1)}{(m+1)^2}\\\\=\dfrac{m^3+m^2-3m-2}{m^2+2m+1}

Circle X has radius r X = 6 units and circumference C X = 12 π units. Circle Y has circumference C Y = 6 units. Which equation i
slega [8]

Answer:

ry=\frac{rx}{2\pi }

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=2\pi r

we have

<em>Circle X</em>

rx=6\ units

Cx=12\pi\ units

<em>Circle Y</em>

Cy=6\ units

Find the radius ry

we know that

Cy=2\pi ry

substitute the value of Cy

6=2\pi ry

ry=\frac{6}{2\pi }

Remember that the value of rx is rx=6\ units

substitute

ry=\frac{rx}{2\pi }
