Correct answer gets brainliest
Ilia_Sergeevich [38]

Answer:

  • sides: isosceles
  • angles: right

Step-by-step explanation:

At first, lets find the distance from one point to the other.

d(A,B)=\sqrt{(x_{A}-x_{B} )^2 +(y_{A}-y_{B} )^2 } \\d(A,B)=\sqrt{(2-0 )^2 +(-2-4 )^2 } \\d(A,B)=\sqrt{4 +36 } = \sqrt{40 } = \sqrt{4 * 10 } = 2\sqrt{10}

The same way, you can find that:

d(A,C)= 2\sqrt{10}\\d(A,B)= 2\sqrt{20}

Since the triangle has only its two sides equal to each other (AB = AC),

it's an isosceles one.

As long as the angles are concerned, we gotta "cheat". In other words, we see that:

AB^2 + AC^2 = (\sqrt{40})^2 + (\sqrt{40})^2 = 40 + 40 = 80\\ AB^2 + AC^2 = 80 = (2\sqrt{20})^2 = BC^2\\AB^2 + AC^2 = BC^2

By the inverse of pythagorean theorem, we know that if the above equation holds, then we have a right-angled triangle. That is to say that,

A = 90

Since its an isosceles triangle, AB = AC,

B = C = (180 - A)/2 = 45 degrees

Where x is the first integer and x+1 is the second integer
x + (x+1) = -49
2x = -50

Find the value of x ?<br><br> A)67<br><br> B)113<br><br> C)77<br><br> D)57
lana [24]

Answer:

<h2>A) 67</h2>

Step-by-step explanation:

The sum of the angles measures at one side of the parallelogram is 180°.

Therefore we have the equation:

x + 113 = 180             <em>subtract 113 from both sides</em>

x + 113 - 113 = 180 - 113

x = 67
