Find the missing sides of the triangle

D

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = , then

sin30° = = = ( cross- multiply )

f = 24

----------------------------------------------------------------

Using the cosine ratio and the exact value

cos30° = , then

cos30° = = = = ( cross- multiply )

2e = 24 ( divide both sides by 2 )

e = 12

F=24 and e=12

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
