Find each error and make the corrections

Exercise 1

1) Δ ABC ≅ Δ EDC

From the figure:

a)    [Given]

b)                                              [Given]

c)    [Vertical angles are congruent]

∴ Δ ABC ≅ Δ EDC                                                [A.S.A postulate]

2) The triangles are congruent by A.S.A postulate.

Exercise 2

1) Δ WXY ≅ Δ ACB

From the figure:

a)    [Given]

b)                                              [Given]

c)    [Given]

∴ Δ WXY ≅ Δ ACB                                                [A.S.A postulate]

2) The triangles are congruent by A.S.A postulate.

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
