Answer:
1.  A = 59
2.  A = 43
Step-by-step explanation:
If we have a right triangle  we can use sin, cos and tan.
sin = opp/ hypotenuse
cos= adjacent/ hypotenuse
 tan = opposite/ adjacent
For the first problem, we know the opposite and adjacent sides to angle A
tan A = opposite/ adjacent
tan A = 8.8 / 5.2
Take the inverse of each side 
tan ^-1 tan A = tan ^-1 (8.8/5.2)
A = 59.42077313
To the nearest degree
A = 59 degrees
For the second problem, we know the  adjacent side and the hypotenuse to angle A
cos A = adjacent/hypotenuse
cos A = 15.3/21
Take the inverse of each side 
cos ^-1 cos A = cos ^-1 (15.3/21)
A = 43.23323481
To the nearest degree
A = 43 degrees
 
        
             
        
        
        
Answer:
3.14 or pi
Step-by-step explanation:
the area of a circle =  where r is the radius of the circle
 where r is the radius of the circle
this is 1/4 of the circle, so it would be 1/4 (pi * r²) 
it shows that the radius is 2, so you have
1/4 ( pi * 2²)
= 1/4 ( pi * 4 )
= 1/4 (3.14 * 4)
= 3.14 units²
