Find the measures of the missing angles.​

m∠1 = 51

m∠2 = 61

m∠3 = 29

Step-by-step explanation:

Hey There!

So the first angle that we want to find is angle 1

They have given us 2 angles and if  you didnt know all of the angles in a triangle will add up to equal 180. So if given 2 angles all we have to do is subtract the given angles from 180 and we get the 3rd angle

180-68-61=51 so m∠1 = 51

Now we want to find angle 2 and angle 2 is vertical to the angle that is equal to 61. If you didnt know vertical angles are congruent to each other therefore m∠2 = 61

Now we want to find angle 3. We know that angle 2=61 and the square on the bottom right of the triangle indicates that its a right angle so its equal to 90

Now like last time we want to subtract the given angles from 180 to find m∠3

180-90-61=29 so m∠3=29

hope this helps :)

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
