The 3 inside angles of a right angled triangle are in the ratio 7; 18; 11. the smallest angle is 35. work out angle ab b c

The angles are  35, 90 and 55

Step-by-step explanation:

Since you mentioned that it is a right triangle, you know that one of them is 90, and the other 35. You then add 90 and 35, getting 125. You subtract 125 from 180 (all triangles are 180  degrees) and get 55

Sum of interior angles of a triangle = 180

ratio 7:18:11

so

7+18+11 = 36

180 / 36 = 5

7 x 5 = 35

18 x 5 = 90

11 x 5 = 55

answer

35, 90 and 55
