\huge \bf༆ Answer ༄

As we know, sum of interior angles of a triangle is 180°

that is ~

  • \sf13x + 2 + 5x - 7 + 3x - 4 = 180

  • \sf21x  - 9 = 180

  • \sf21x = 180 + 9

  • \sf x =  \dfrac{189}{21}

  • \sf x = 9 \degree

Hence, value of x is 9°

Answer:

  • x = 9

Step-by-step explanation:

<u>Sum of interior angles is 180:</u>

  • (13x + 2) + (5x - 7) + (3x - 4) = 180
  • 21x - 9 = 180
  • 21x = 189
  • x = 189/21
  • x = 9

sleet_krkn [62]

Answer:

19,200 yds²

Step-by-step explanation:

The question is asking for how many <em>square yards</em> of grass is needed

This means that it is looking for the Area.

The formula for area is <em>Length x Width = Area</em>

<em>120</em> (Length)

<em>160</em> (Width)

<em>120 x 160</em> = 19,200

The unit of measurement is yards...

19,200 yds²

Write an equation which is perpendicular to the line of y= -5/2x+2​
S_A_V [24]

Answer:

y = 2/5x

Step-by-step explanation:

Perpendicular lines are lines which have negative reciprocal slopes of each other.

The line y = -5/2 x + 2 has slope -5/2. Therefore its perpendicular slope will be 2/5.

The equation can cross anywhere on the y-axis for its y-intercept since no specific point is given. Here I chose (0,0).

y = 2/5x

Enter the solution (x,y) to the system of equations shown.<br> y= -6<br> y= 4x+12
andriy [413]
Y= -6 --> plug this -6 into the y of the 2nd equation
y= 4x+12 --> -6 = 4x+12 --> 4x = -18
x = -18/4 = -9/2 --> now this is the x solution coordinate, and we know that y must equal -6 from the 1st equation, so our solution point is:
(-9/2, -6)
Hope that helped!
