Which equation could be used to find the perimeter of an isosceles triangle, with two sides 13 cm long, a base 10 cm long, and a height of 12 cm? a. p = (10 × 12) ÷ 2 b. p = 2 × 13 + 10 c. p = 13 + 10 + 12 d. p = 2 × 10 + 13

this answer is !

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
