We know that ∠1 equals ∠3, from that we can find x:

10x = 100 \\ x = 10

The sum of ∠1 and ∠2 must equal 180°:

10x + 10y + 20 = 180

Since we already know x, we can solve for y:

10 \times 10 + 10y + 20 = 180 \\ 10y + 120 = 180 \\ 10y = 60 \\ y = 6

Result: x=10, y=6

Answer:

Market price $400

Cost price $300

Step-by-step explanation:

MP: market price

CP: cost price

1. (MP x 0.9) - CP = 60

CP = 0.9MP - 60

2. MP - CP = 100

CP = MP - 100

0.9MP - 60 = MP - 100

MP - 0.9MP = 100 - 60

0.1MP = 40

MP = 400

Cost price = MP - 100 = 400 - 100 = 300

What is the slope of the line that
Naily [24]

Answer:

The line has a slope of zero which means the line is a horizontal line.

Step-by-step explanation:

Given that:

The two points are (-3,2) and (4,2)

Slope of a line is given by the formula,

m = \frac{Rise}{Run} = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

Here,

x_{1}=-3,\ y_{1}=2\\x_{2}=4,\ y_{2}=2

Putting these values in formula;

m=\frac{2-2}{4-(-3)} \\m = \frac{0}{4+3}\\m = \frac{0}{7} = 0

Hence,

The line has a slope of zero which means the line is a horizontal line.
