Answer:
A
Step-by-step explanation:
two complementary that have the same measure angels always equals 90
Answer:
C
Step-by-step explanation:
Using the sine ratio and the exact value sin45° = 
, then
sin45° = 
= 
= ( cross- multiply )
a = 6
Using the tangent ratio and the exact value tan45° = 1 , then
tan45° = 
= 
= 1 , so
b = 6
