Answer:
119 is the answer
Step-by-step explanation:
use sum of angles on a straight line
Pythagorean Theorem is for right triangles
right triangles have a 90 degree angle in them
D is a right triangle
The total 'parts' of the ratio is 10 (3+7).
Complementary angles add to 90 degrees.
Divide 90 by 10 and you get 9.
Each 'part' is 9.
3:7 * 9 = 27:63
One angle is 27 degrees and the other is 63 degrees.
