If you are just looking for any number between you can go from 144.810 to 145.154 and you can get even more number if you add a zero to both number because there are lots more between 145.1550 and 144.8090
However, if you are looking for the number that is equidistant between them - the number in the middle, simply add them together and find the average which will be the number in the middle.
So
(145.155 +144.809)÷ 2 = 144.982
154 degrees; when you add up the two angles you get 154 subtract that from 180 which is the sum of a triangle. You should get 26 for the third angle of the triangle. when you extend the segment if MH you form an X the acute angle of the X are 26 to find H you subtract 26 from 180 since a straight line is 180 and you get 154 for the abtuse angles which is also H
45 because 270 + 45 =315 . So 360-315= 45
