Question

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

Answer 1

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

Answer 2

The angles are 35, 90 and 55

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
