Answer: ∠AOB = 100°

Step-by-step explanation:

This is found in the circle geometry. The theorem in solving this stated that the angle which an arc of a circle subtends at the centre  of the circle is twice that which  it subtends at any point on the remaining part of the circumference of the circle

Therefore

∠AOB = 2 x ∠ACB

           = 2 x 50°

           = 100°

Consider the incomplete paragraph proof.
Leya [2.2K]

The hypotenuse is c = a\sqrt{2}  times the length of each leg 'a'. Triangle XYZ is a isosceles right triangle, therefore the Pythagoras theorem becomes  and this can be evaluated by using properties of isosceles triangle.

According to the statement

we have given that a theorem and we have to prove it.

So, For this purpose,

The given information is :

Isosceles triangle XYZ where Angle X = 45^{0} Angle Y = 45^{0} Angle Z = 90^{0}

Let the sides of triangle XYZ be a, b, and c. Then side XY = c, YZ = b and ZX = a.

Now, it is given that triangle XYZ is isosceles triangle therefore, the shorter sides must be equal that is, a = b.

Now use Pythagoras theorem

a^{2} + b^{2} = c^{2}

But here a= b then the equation become

a^{2} + a^{2} = c^{2}

Then after solving it become

2a^{2} = c^{2}

And here we have to find the value of the hypotenuse,

so we solve it for c.

Then

c = a\sqrt{2}

From this it is clear that the

it can be concluded that the hypotenuse is  times the length of each leg 'a'.
