Can someone help me solve this triangle (geometry) question?

a is the correct

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

i think that you should ask google for the answer to that problem because if we don't know it google does

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
