Answer:

Step-by-step explanation:

b/c this is an isosceles triangle we know that either leg is the same length.. so we can use many trig functions :)

SOH CAH TOA to remember how trig functions fit on the triangle...

we know the hypotenuse and the angle and we want to find the adjacent leg ( which for this triangle is also the opposite leg )

use Cos = Adj / Hyp

Hyp*Cos(45) = adj

16* $\sqrt{2}/2$ = adj

8* $\sqrt{2}$ = adj

each leg is the same $8\sqrt{2}$

Question 3

hoa [83]

answer is (-7,2)

y = -x -5

y= x+9

Both equations have y on the left hand side

So we equate both equations

We replace -x-5 for y in the second equation

-x -5 = x+9

Subtract x on both sides

-2x -5 = 9

Now add 5 on both sides

-2x = 14

Divide by -2 from both sides

x = -7

Now plug in -7 for x in the first equation

y = -x -5

y = -(-7) -5= 7-5 = 2

So answer is (-7,2)
