Question:
Genrish500 [490]

Answer:

x=56 and the exterior angle is 116

Step-by-step explanation:

We will call the unknown angle in the triangle y.  Angle y and the angle (2x +4) form a straight line so they make 180 degrees.

y + 2x+4 =180

Solve for y by subtracting 2x+4 from each side.

y + 2x+4 - (2x+4) =180 - (2x+4)

y = 180-2x-4

y = 176-2x


The three angles of a triangle add to 180 degrees

x+ y+ 60 = 180

x+ (176-2x)+60 = 180

Combine like terms

-x +236=180

Subtract 236 from each side

-x+236-236 = 180-236

-x = -56

Multiply each side by -1

-1*-x = -56*-1

x=56

The exterior angle is 2x+4.  Substitute x=56 into the equation.

2(56)+4

112+4

116

What is the slope intercept form of (-1,-1) and (-4,-1)
liubo4ka [24]

Answer:

y=-1

Step-by-step explanation:

use point slope formula y-y₁=m(x-x₁)

find m which is slope  -1--1/-4--1= 0/-3= 0

plug in the equation and use the first point

y--1=0(x--1)

y=-1

   Then we will use the equation that
                  1 gallon = 3.8 lires
Then by using this we will calculate the amount of cup used by equalizing with litres and then by gallons and then calculate number of cups in gallons
