Answer:

a = 4

b = 2√2

Step-by-step explanation:

First, we will calculate the sine of 45°, which is equal to the length of the opposite side (2√2) divided by the length of the hypotenuse (a).

sin 45° = 2√2 / a

a = 2√2 / sin 45°

We know than sin 45° = √2/2

a = (2√2) / (√2/2) = 4

Then, we calculate the tangent of 45°, which is equal to the length of the opposite side (2√2) divided by the length of the adjacent side (b).

tan 45° = 2√2 / b

b = 2√2 / tan 45°

We know that tan 45° = 1

b = 2√2 /  1 = 2√2

Right triangle 45 45 90
so b = 2√2

and
a^2 = (2√2)^2 +  (2√2)^2
a^2 = 8 + 8 
a^2 = 16
a = 4

Find f(-4) if f(x) = 3x - 6.<br><br> A 6<br> B -6<br> C 18<br> D -18
brilliants [131]

Answer:

f(-4) = -18

Step-by-step explanation:

f(-4)  means x = - 4

So Plug in x = - 4 into f(x) = 3x - 6

f(-4) = 3(-4) - 6

= -12 - 6

= -18

So

f(-4) = -18

If 2x + 5 = 82, then 12x = ?<br> A 5<br> B<br> 10<br> C 15<br> D 20
KengaRu [80]

Answer:

2x= 38.5

Step-by-step explanation:

I'm not sure where u got 12x but 2 x = 38.5:

2x + 5 =82

subtract 5 for 82

2x = 77

77 divided by 2 is 38.5

x = 38.5

hope this helps :)
