Answer:

Total area of field sold(35*35)+(51*25)=2500

Area of square field is 2500

One side = \sqrt{a} = 50

So, the perimeter of the square(4*a)=4*50=200

Cost of fencing = 200*1.5 usd = $300

two adjacent angles of a parallelogram are in the ratio 5:2: . find all the angles of the parallelogram​
kicyunya [14]

<h2>Given :-</h2>

  • Two adjacent angles of a parallelogram are in the ratio of 5 : 2.

<h2>To Find :-</h2>

  • What is the all angles of the parallelogram.
<h3 /><h3 /><h2>Solution :-</h2>

Let, the first angles be 5x

And, the second angles will be 2x

As we know that,

★ Sum of all angles = 180° ★

According to the question by using the formula we get,

  • ⇒ 5x+2x=180°

  • ⇒7x=180°

  • ⇒ \sf x =\: \dfrac{\cancel{180^{\circ}}}{\cancel{7}}

  • ➠ \sf\bold{\red{x =\: 25.7^{\circ}}}

Hence, the required angles are,

  • First angles = 5x = 5(25.7°) = 128.5°
  • Second angles = 2(25.7°) = 51.4°

As we know that, 

opposite angles in a parallelogram

is equal.

∴ The all angles of a parallelogram is 128.5°,51.4°, 128.5° and 51.4°.

Find the x intercept and the y intercept of the graph of the equation <br> 2x+4y=8
maksim [4K]

Answer:

x-intercept: 4

y-intercept: 2

Step-by-step explanation:

finding the x-intercept:

first, substitute y = 0.

2x + 4 x 0 = 8

then, remove the 0.

2x + 0 = 8

then, divide both sides. 2x = 8

so, x = 4.

finding the y-intercept:

first, substitute x = 0.

then, solve.

2 x 0 + 4y = 8

so, y = 2.
