The angles of a triangle are 80°, 2x + 2°, and 5x°.
Bezzdna [24]
The sum of interior of all angles in a triangle = 180
Given 3 angles = <span>80°, 2x + 2°, and 5x°
To find x:

</span><span>80°+  2x + 2 +  5x = 180
7x + 82 = 180
        7x = 98
          x = 14

answer
x = 14 </span>

Cindy is make a display for a project. She plans on 100 stickers that are 2 inch by 2 inch square on a poster board. The poster
gavmur [86]

Answer:

YES

Step-by-step explanation:

the dimensions of the poster board has to be converted to inches to add comparability

1 feet = 12 inches

3 x 12 = 36 inches

width = 2 x 12 = 24 inches

Area = length x breadth

36 x 24 = 864 cm^2

area of sticker = 2 x 2 = 4cm^2

Number of stickers that can be put on the board = 864 / 4 = 216

216 is greater than 100. So the board has enough room for the stickers

Find an equation of the circle whose diameter has endpoints ( −1,−4) and (3,2) .
const2013 [10]
The equation of a circle is:

(x-h)^2+(y-k)^2=r^2, where (h,k) is the center and r is the radius

So the first thing we can do is to find the center of the circle, which will be at the midpoint of the two endpoints of the diameter.  The midpoint is simply the average of the coordinates of the endpoints.

mp=((-1+3)/2, (-4+2)/2)

mp=(1, -1), and this midpoint is the center of the circle our (h,k) for the circle equation.

Now we must find the length of the diameter so that we can know what our radius is.  The distance between any two points is:

d^2=(x2-x1)^2+(y2-y1)^2 so

d^2=(-1-3)^2+(-4-2)^2

d^2=4^2+6^2

d^2=16+36

d^2=52

Note that this distance squared is our diameter squared.

Since d=2r

d^2=4r^2

r^2=d^2/4, we showed that d^2=52 so

r^2=52/4 

r^2=13  (r=√13, but we need r^2 for our equation anyway)

So now we can fill out our circle equation because we know the center is at (1,-1) are r^2=13

(x-1)^2+(y+1)^2=13
