Which of the following is a true polynomial identity? a) 28 -66 = (a? – 62)(a? - ab +62)(a2 + ab +62)
b) a
b® = (a3-b})(a - ab + b)(a² + ab +62
c) a+b = (a?+62)(a4 + a²b2+ b^)
d) 26–68 = (a?+62)(a? - ab+b2/a?+ ab +62

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

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
