Novosadov [1.4K]

Answer:

AB= 36 degrees

Step-by-step explanation: AB + BC + AC = 96

but AB = AC  [isosceles triangle]

2AB + 24 = 96

2AB = 96 - 24 = 72

AB = 72/2 = 36

AB = 36 degrees.

What two numbers multiply to -120 and add to -2
USPshnik [31]

Hello!

To answer this question we need to find the factors of -120.

The total set (both negative and postive! ) are the following:

  • 1, -120
  • 2, -60
  • 3, -40
  • 4, -30
  • 5, -24
  • 6, -20
  • 8, -15
  • 10, -12
  • 12, -10
  • 15, -8
  • 20, -6
  • 24, -5
  • 30, -4
  • 40, -3
  • 60, -2
  • 120, -1

After looking over all of these factors, we can see that 10 · -12 is equal to not only -120, but when the multiplication sign is replace by addition, it is equal to -2!

Hope this helps.

Given: KLMN is a trapezoid m∠K = 90°, m∠N = 45° LK = LM = 10 Find: KN, Area of KLMN
Ilya [14]
Let KLMN be a trapezoid (see added picture). From the point M put down the trapezoid height MP, then quadrilateral KLMP is square and KP=MP=10.
A triangle MPN is right and <span>isosceles, because
</span>m∠N=45^{0}, m∠P=90^{0}, so m∠M=180^{0}-45^{0}-90^{0}=45^{0}.Then PN=MP=10.
The ttapezoid side KN consists of two parts KP and PN, each of them is equal to 10, then KN=20 units.
Area of KLMN is egual to A= \frac{LM+KN}{2} *MP= \frac{10+20}{2} *10=150 sq. units.
