The interior angles of any convex quadrilateral add up to 360º in measure.

This means angle 1, whose measure is 42.5% of this total, has measure 0.425*360º = 153º.

Similarly, angle 2 has measure 0.075*360º = 27º, and angle 3 has measure 0.175*360º = 63º.

So

153º + 27º + 63º + <em>x</em>º = 360º  ==>  <em>x</em> = 117

Write an equation of the line below
gregori [183]

Answer:

The equation of the line is:

y = 4x + 3

Step-by-step explanation:

We know that the slope-intercept of line equation is

y = mx+b

Where m is the slope and b is the y-intercept

Given the two points on a line

  • (0, 3)
  • (-2, -5)

Finding the slope between (0, 3) and (-2, -5)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(0,\:3\right),\:\left(x_2,\:y_2\right)=\left(-2,\:-5\right)

m=\frac{-5-3}{-2-0}

m=4

We know that the y-intercept can be computed by setting x=0 and determining the corresponding y-value.

From the graph, it is clear:

at x = 0, y = 3

Thus, y-intercept = b = 3

Substituting m = 4 and b = 3 in the slope-intercept form of line equation

y = mx+b

y = 4x + 3

Therefore, the equation of the line is:

y = 4x + 3

The sample space, S, for flipping a fair coin three times is shown
Ksenya-84 [330]

Answer: \frac{7}{8}

Step-by-step explanation:

Given

Sample space is ={HHH,THH,HTH,HHT,TTH,THT,HTT,TTT}

There are 8 element in sample space which indicates the outcome of tossing a coin three times

Probability of obtaining at least one head=1-P(\text{0 head})

P(\text{0 head})=P(\text{All tails})

P=1-\frac{1}{8}

P=\frac{7}{8}

The car cost $4,155 and she has $1,575 so $4,155-$1,575=$2,580as the balanced owed if she borrows the rest from her parents and has a one year to pay it off it will be paid off because her payments are $225 a month for one year  at 225x12=$2,700 its a little over but it will be paid off
