Find the ratio of x to y.​

29: 7

Step-by-step explanation:

Cross multiply:

Expand bracket:

Bring x terms to 1 side, y terms to the other:

Simplify:

Divide by 7 on both sides:

Divide both sides by y:

∴ The ratio of x to y is 29:7.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

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°
