What is the GCF of 132 and 432

12

Step-by-step explanation:

Find the prime factorization of 132

132 = 2 × 2 × 3 × 11

Find the prime factorization of 432

432 = 2 × 2 × 2 × 2 × 3 × 3 × 3

To find the gcf, multiply all the prime factors common to both numbers:

Therefore, GCF = 2 × 2 × 3

GCF = 12

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°
