What are the exact values of a and b

d) a = 5 ; b = 5√3

Hi there !

30°-60°-90°  Theorem

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 !

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
