Answer:
m∠1 = 51
m∠2 = 61
m∠3 = 29
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 :)
