Is Anyone know the answer?

Angle 1 = 40

Step-by-step explanation:

Angle 1 and Angle 2 are alternate angles. So,

2x + 20 = 3x + 10

3x - 2x = 20 - 10

x = 10

Angle 1 = 2x + 20 = 2 x 10 + 20 = 40

∠1 = 10°

Step-by-step explanation:

                           ∠1 = ∠2

                  2x + 20 = 3x + 10

2x + 20 + (-3x - 20) = 3x + 10 + (-3x - 20)

                            -x = -10

                             x = 10

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
