Answer:
sin (theta) = 
cos (theta) = 
tan (theta) = 
cot (theta) = 7 square root 15/15
sec (theta) = 
csc (theta) = 8 square root 15/15
Step-by-step explanation:
19.625cm squared because you have to divide the diameter by 2 to get the radius.
area of circle=pi times radius times radius
=3.14 times 2.5 times 2.5
=19.625cm squared

Step-by-step explanation:
Answer:
∠6=78° ∠7=102° ∠14=78°
Step-by-step explanation:
Angles 6 and 7 are supplementary angles so ∠a+∠b=180°
in this case it would be 102°+x=180° and you subtract 102° from 180° getting 78°
∠7 is the vertical angles postulate stating that any angles vertical to each other are eaqual
