Answer:

Step-by-step explanation:

Circum center of a right isosceles triangle is located on the midpoint of the hypotenuse.

Circumcenter of a triangle is point where  the perpendicular bisectors of the sides of triangles intersect. Keeping this as a center, you can draw a circle & all the three vertices of the triangle lies on the circumference of the circle. Circumcenter is equal distance from the vertices of the triangle.

For acute triangle, circumcencenter will be inside the triangle.

For obtuse triangle, circumcenter will be outised the triangle.

Lets look at examples where the circumcenters are located:

  • In a obtuse isosceles triangle, the circumcenter is always outside the triangle.
  • In a right isosceles triangle, the circumcenter is located on the midpoint of the hypotenuse. The hypotenuse is the longest side and midpoint means the middle.
  • In a acute isosceles triangle, the circumcenter is located outside, inside, or on the triangle.

Best of Luck!

What value in place of the question mark makes the polynomial below a perfect square trinomial 9x^2+?x+64
timurjin [86]

Answer:

The middle term would be 48x

Step-by-step explanation:

In order to find this, we need to take the squares of the end terms and put them in a perfect square. Then we can distribute to find the middle term.

(3x + 8)^2

(3x + 8)(3x + 8)

9x^2 + 24x + 24x + 64

9x^2 + 48x + 64

Lines b and care parallel.
Vinil7 [7]

Answer:

<h3>Option 2 </h3>

angle 2 = 7x + 1 ( vertically opposite angles)

7x + 1 + 18x + 4 = 180° ( forming linear pair).

7x + 18x + 4 +1 = 180°

25x + 5 = 180°

25x = 180 - 5

25x = 175

x = 7°

angle 2 = 7(7)+ 1

= 50°

Need to find the number for a
Shalnov [3]
Answer to the first triangle: 15

To solve this we will use the Pythagorean theorem

Pythagorean theorem formula: a^{2} +  b^{2} =c^{2}

Lets do the first triangle. 

17 is the hypotenuse, so its going to replace c in the formula.

8 is the height and it is going to replace a in the formula.

a is what we are trying to find, so our b in the equation is going to be the unknown.

8^2 + b^2 = 17^2

64 + b^2 = 289&#10;&#10;

b^2 = 289 - 64

b^2 = 225

\sqrt{b^2}  =  \sqrt{225}

b = 15

now we know that the missing length in the first triangle (a) is 15

Can you solve the Other one?

Just comment if you need help on the other one.
