An angle measured 42 degrees less than the measure of its supplementary angle. what is the measure of each angle?

138°

Step-by-step explanation:

180° is a supplementary angle and if it's 42° less it would be 138° 180-42=138

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

320ft

step-by-step explanation:

120 divided by 3 equals 40

40 times 4=160

160 times 2=320
