You put $5,000 in a simple interest account at a bank. You earn $1,200in just 4 years. What is the annual interest rate for the account?

6%

Step-by-step explanation:

To solve this problem we can use a modified version of the simple interest formula which is shown below:

I = interest amount

P = principal amount

t = time (years)

Now, lets plug in the values:

The last step is to convert 0.06 into a percent:

0.06(100) = 6

The interest rate is 6%.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

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°
