Answer:
Step-by-step explanation:
Use Pythagoras’ theorem
square of hypotenuse = sum of squares of two other sides
let the missing side be d
30^2 = 20^2 + d^2
600 = 400 + d^2
d^2 = 200
d = square root of 200
d = 14.142 cm
If this an angle on a straight line the answer is k=73°
Pythagorean Theorem is for right triangles
right triangles have a 90 degree angle in them
D is a right triangle
