Answer:
62
Step-by-step explanation:
Angle Formed by Two Chords
= 1/2(sum of Intercepted Arcs)
RST = 1/2 ( 47+77)
= 1/2 (124)
= 62
Answer:

Step-by-step explanation:
We have,
Radius of the circle is 12 cm
Arc length, l = 21 cm
It is required to find the central angle of the circle. The formula for the length of an arc of a circle is :

is central angle

So, the angle at the centre of the circle is
.
(12 x 2) - 5 because twice as many means to multiply by 2. fewer means to subtract.
