1 is 69 degrees. 2 is 111 degrees

Step-by-step explanation:

1 is 69 because when a line intersects with 2 paralell lines, 1 and the 69 degree angle are the same degree. we know that the second angle plus 69 degrees is 180, so 180-69 is 111.

Question:

what are the options on the sides?

1: 69 by the      ?

2: 111 by the      ?

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
