Answer:
1) 61
2) 124
3) 27
4) 29
Explanation:
Angle 1)
This one is quite simple
add 63 and 56 together

now minus 119 from 180 because the all the interior angels of a triangle must equal 180 degrees

angle 2)
minus 56 from 180 because the angles are on a straight line. angles on a straight line must equal 180 degrees

angle 3)
since the angel is 90 degrees and on side is 63 degrees just minus 63 from 90

angle 4)
add sum of angle 3 and 2 then minus the total from 180 to find angle 4
