Find the value of x and please show how

Rzqust [24]

Answer:

?=91 degrees.

Step-by-step explanation:

There is no x- I'll find ? though.

So, angles in a triangle must equal 180.

180-29-62=89. The last angle in the triangle is 89 degrees.

A straight angle is equal to 180 degrees. ? + 89=180.

180-89=91.

?=91 degrees.

Hope this helped!

What are the possible rational zeros of f(x)=x^4+2x^3-3x^2-4x+20?

Mice21 [21]

Roots test tells us to take the factors of the 20 divided by the factors of the coefficient of the the first.

factors of 20 are 1,2,4,5,10,20
factors of 1 are 1

so plus or minus 1/1, 2/1, 4/1, 5/1, 10/1, 20/1 are all possible rational zeros

Find the missing measure for a right circular cone given the following information.

xxTIMURxx [149]

<h2>Answer:</h2>

The radius of the cone is:

$r=\dfrac{2}{\sqrt{\pi}}$

<h2>Step-by-step explanation:</h2>

The total area of cone is given by:

$T.A.=\pi r(l+r)=\pi rl+\pi r^2=12---------(1)$

where r is the radius of the cone and l is the slant height of the cone.

and the lateral area of cone is given by:

$L.A.=\pi rl=8---------(2)$

Hence, from equation (1) and (2) we have:

$8+\pi r^2=12\\\\\\i.e.\\\\\\\pi r^2=4$

i.e.

$r^2=\dfrac{4}{\pi}$

i.e.

$r=\dfrac{2}{\sqrt{\pi}}$
