d) a = 5 ; b = 5√3
- Step-by-step explanation:
Hi there !
30°-60°-90° Theorem
- side opposite the 30° angle = a
-
side opposite the 60° angle => b = a√3
-
side opposite the 90° angle = 2a
1)
side opposite the 90° angle = 2a
10 = 2a => a = 10/2 => a = 5
2)
side opposite the 60° angle => b = 5√3
Good luck !
