Can you draw an isosceles triangle with only one 80 degree angle?
aev [14]

Answer:

The triangle is 50,50 80

Step-by-step explanation:

The three angles of a triangle equal 180 degrees

We only want one 80 degree angle.  That means the other two angles have to be the same, since it is an isosceles triangle.  Call the other angle x

x+x+80 = 180

2x+80 =180

Subtract 80 from each side

2x+80-80=180-80

2x =100

Divide by 2

2x/2=100/2

x = 50

Each of the other angles in the triangle would have to equal 50 degrees

The triangle is 50,50 80

Solve each problem and check your answer using estimates. a. $18.79 + $2.11 + ‐$1.92 + $17.28 b. $7.45 + ‐$24.45 + $74.17 + ‐$76
Aneli [31]

The solution to the linear expressions are:

  • a. $36.26
  • b. -$19.35
  • c. $70.38

<h3>Solving linear expressions:</h3>

The solution to linear expression is determined by taking into consideration the arithmetic operations used in each linear expression.

From the information given:

a. $18.79 + $2.11 + ‐$1.92 + $17.28

By rearrangement:

= $18.79 + $2.11 + $17.28 ‐$1.92

= $36.26

b. $7.45 + ‐$24.45 + $74.17 + ‐$76.52

By rearrangement:

= $7.45  + $74.17 ‐ $24.45 ‐ $76.52

= -$19.35

c.  $98.45 − $10.63 + $2.82 − $20.26

By rearrangement:

= $98.45 + $2.82 − $10.63 − $20.26

= $70.38

the perimeter of football field in a rectangular form of a certain school is 296cm if the breath is2/3 of the length find the le
Pani-rosa [81]

Answer:

L = 29.6 cm

Step-by-step explanation:

Let Length be L and Breadth be B

<u><em>Condition 1:</em></u>

2(Length)+2(Breadth) = Perimeter

Where Perimeter = 296 cm

=> 2L + 2B = 296

=> 2(L+B) = 296

<em>Dividing both sides by 2</em>

=> L + B = 148   ------------------(1)

<u><em>Condition 2:</em></u>

=> B = \frac{2}{3} L  -------------------------(2)

Putting Equation 2 in 1

=> L + \frac{2}{3} L  = 148

Multiplying both sides by 3

=> 3L + 2L = 148

=> 5L = 148

=> L = 148/5

=> L = 29.6 cm
