52°

Step-by-step explanation:

If it is a right triangle, one interior angle is 90°, and we are also given the interior angle of 38°. The sum of any triangles interior angles will always be 180°.

90 + 38 = 128

180 - 128 = 52

The third angle is 52°

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
