Answer 4

use this :-

external angle = (far arc - near arc)/2

Answer 5

so I have to find arcRT first?

Answer 6

yes, near arc RT = 2x inscribed angle

Answer 7

you're given inscribed angle S = 30, so...

Answer 8

oh, so would m<U = 12 degrees?

Answer 9

Answer 10

good work !!

Answer 11

could you help me with another one?

Answer 12

sure

Answer 13

Find the value of x for the measure of arcAB = 27° and the measure of arcCD = 49°. The figure is not drawn to scale

Answer 14

I think it is 38 degrees. I'm not sure tho

Answer 15

38 is right,
may i knw how u got that ha ?

Answer 16

(27 + 49)÷2

Answer 17

thats correct formula !

Answer 18

Find m<D for m<B = 65°. The figure is not drawn to scale

Answer 19

hint : radius and tangent make 90 degree angle

Answer 20

hint2 : sum of angles in a quadrilateral = 360

Answer 21

OH!! Sorry I remember how to do this now. hold on

Answer 22

good :) let me knw if u need more hints lol

Answer 23

it can be tricky :o

Answer 24

is it 115°?

Answer 25

115 = \(\large \color{red}{\checkmark}\)

Answer 26

A park maintenance person stands 16m from a circular monument. Assume that her lines of sight form tangents to the monument and make an angle of 47 degrees. What is the measure of the arc of the monument that her lines of sight intersect?
