Answer:
100 degrees just think about how all the angles in a triangle add up to 180 degrees

Answer:

See below in bold.

Step-by-step explanation:

1. The 3 angles in a triangle add up to 180 degrees.

So x = 180 - (55 + 25)

= 180 - 80

= 100 degrees.

2. The 4 angles in a quadrilateral add up to 360 degrees,, so

3x + 127 + 54 + 119 = 360

3x + 300 = 360

3x = 360 - 300

3x = 60

x = 20 degrees.

3. Exterior angle

= 94 + 42

= 136 degrees.

You brought 9 feet of elastic to make hair ties each hair ties need 3 3/8 inches of elastic how many hair ties can you make

PIT_PIT [208]

Answer:

$32\ hair\ ties$

Step-by-step explanation:

we know that

To make one hair ties is needed 3 3/8 inches of elastic

using proportion

Find out how many hair ties can you make with 9 feet of elastic

Remember that

$1\ ft=12\ in$

Convert 9 ft to inches

$9\ ft=9*12=108\ in$

Convert mixed number to an improper fraction

$3\frac{3}{8}\ in=\frac{3*8+3}{8}=\frac{27}{8}\ in$

using proportion

$\frac{1}{(27/8)}=\frac{x}{108}\\\\x=108*8/27\\\\x=32\ hair\ ties$

what equation in slope intercept form for the line that passes through point (8,-3) and has a y intercept of -2

JulijaS [17]

Answer:

y=-8x-2

Step-by-step explanation:

The formula for slope is y2-y1/x2-x1. Take coordinate (0,-2), which is the y-intercept. We'll call that (y2,x2). Coordinate (8,-3) is (y1,x1). Put that into the formula you get, 0-8/-2-(-3). You get -8/1 which is negative 8. We now have the slope. Slope intercept form equation is y=mx+b. M is slope, so we put our slope in the equation and get, y=-8x+b. B is the y-intercept which is given. So we know that the equation to this line in slope-intercept form is y=-8x-2.
