Call the three angles of a triangle ∠1,∠2,∠3

The measure of ∠2 is forty degrees less than that of ∠1; the measure of ∠3 is ten degrees less than twice that of ∠1If x is the measure of ∠1, then which of the following equations would we need to solve in order to calculate the measures of the angles?

              ° is the measure of ∠.

              ° is the measure of ∠.

              ° is the measure of ∠.

Step-by-step explanation:

Given that,

      is the measure of ∠.

Now,

      The measure of ∠ is forty degree less than that of ∠, so () is the measure of ∠.

      The measure of ∠ is ten degree less than twice that of ∠, so () is the measure of ∠.

So,

     According to Angle sum property,

   Sum of the measures of the three angle of triangle is °.

Now,

        ∠ + ∠ + ∠ = °

        () + () + () = °

        °

        °

        °

So,

   ° is the measure of ∠.

   ° is the measure of ∠.

   ° is the measure of ∠.

idk idk idk idk idk

step-by-step explanation:

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
