Hello
(n-2)*180 where n is the number if angles in a polygon
(38-2)*180
=36*180=6480

(29-2)*180=4860
1 angle -> 4860/29 = 167.58

You do the same here
(1026-2)*180=184,320
184,320/1026=179.64

They're complementary so 180-179.64=0.36°

(36-2)*180=6120
6120/36=174.85
180-175.85=5.15°

Step-by-step explanation:

Given : Expression $-1\frac{5}{2}-\frac{7}{12}$

To find : Subtract the expression ?

Solution :

Step 1 - Write the expression,

$-1\frac{5}{2}-\frac{7}{12}$

Step 2 - Write mixed form into proper form,

$-1\frac{5}{2}-\frac{7}{12}=-\frac{7}{2}-\frac{7}{12}$

Step 3 - Take least common denominator,

$-1\frac{5}{2}-\frac{7}{12}=\frac{-42-7}{12}$

Step 4 - Solve,

$-1\frac{5}{2}-\frac{7}{12}=\frac{-49}{12}$

$-1\frac{5}{2}-\frac{7}{12}=\frac{-49}{12}$
