an arch in the shape of a semicircle is to be set up at the entrance of a festival the distance around the arch is about 110 ft what is the height of the arch in feet round your answer to the nearest whole number

35

Step-by-step explanation:

circumference is pi x diameter since this is a semi circle you then divide it by 2

so if you work backwards 110x2 = 220 divided by pi

then you get the diameter and divide it by 2 to find the radius

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
