In the figure AB =6cm, triangle AOB =60° 1) FIND TRIANGLE OAB
2) FIND TRIANGLE OBA
3) FIND THE RADIUS OF THE CIRLCLE.

[THNKS FOR WATCHING MY QUSTION AND PLS FOLLOW PLS FOR THE HARD AND EASY QUSTION ]

From the basics of algebra,

a triangle subtended to the center of a circle from the circumference is always isosceles

since the Central angle is 60 and the triangle is isosceles, the other angles are,

meaning that the triangle is equilateral.

all the other angles are 60.

the radius of the circle is the length of the triangles side,

ie 6cm

idk

step-by-step explanation:

maybe try   if it is work from a book, if not try

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
