Answer:

D). 4\sqrt{2}

Step-by-step explanation:

<u>STEP 1a:</u> Find the last angle of the triangle. ( which is angle A)

A+90+45=180

<u>STEP 1b:</u> Solve the equation for A by adding 90 and 45.

A+135=180

<u>STEP 1c:</u> Then Move all terms not containing A to the right side of the equation by subtracting 135 from both sides of the equation

A=180-135

<u>STEP 1d:</u> Subtract 135 from 180.

A=45

STEP 2a: Find side b next.

STEP 2b: The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

cos(A)=\frac{adj}{hyp}

STEP 2c: Substitute the name of each side into the definition of the cosine function.

cos(A)=\frac{b}{c}

STEP 2d: Set up the equation to solve for the adjacent side, in this case b.

b=c*cos(A)

STEP 2e: Substitute the values of each variable into the formula for cosine.

b=8*cos(45)

STEP 2f: Cancel the common factor of 2.

a=4\sqrt{2}

HOPE THIS HELPS!

Which equation does not represent a function?
kati45 [8]

Answer:

D x2 + y2 = 4

Step-by-step explanation:

The following are the functions

y = 4

y = x - 4

y = x^2 - 4

but

x^2 + y^2 = 4 is not a function as there should be minimum one x value with two or more y values

But the above equation does not meet the criteria so this represent non-function

How do you solve this?
lesantik [10]

Answer:

so for one, just put a line horizontal to line 1

part two I'm assuming you do the same as p since it's not asking you to make it perpendicular to line 1.

part three, create going through line 1 (vertical)

part four constructs the same triangle, but just move the points a little so that way it's not overlapping.

Step-by-step explanation:

parallel means not touching

perpendicular means crossing each other paths.

Can someone PLEASE help me
agasfer [191]
1/5

because 12/60 simplified is 1/5

When scaled down to a smaller shape and you need to find the scale factor, all you need to do is take corresponding sides and divide the smaller shape side by the larger shape side.
Sides that you could also use for the scale factor 12/60, 18/90, there is one more but the mouse is in the way I’ll assume that it’s 15/75, I could be wrong on that one though. I hope this helps.
