Answer:

AB || CD

Step-by-step explanation:

Remember that vertical angles are always equal/ congruent to each other

Since 108° is vertical to angle S, angle S also equals 108°

Since a line is equal to 180°, and you now know that S equals 108°, you would subtract 180 by 108 to get line RT.

180-108= 71°

By default, line VW also equals 71° (you are repeating the same progress you did to get RT)

The angle vertical to <V is equal to 134°, so angle V also equals 134°

180-134 gives you the answer to the angle by 134 and V, they should equal 46°

Corresponding angles equal each other, so angle R is also 134°, and by default the other numbers are equal to to what you did at the top right

Once again, since corresponding angles are equal to each other, you would automatically have the same answers for the bottom line;

the outermost angles equal 134° and the innermost angles equal 46°

I need help i'm really stuck
Ivenika [448]

Answer:

8

Step-by-step explanation:

If the area is 32 and the formula for area of a triangle is base * height / 2, and you have base = 8 and height = x and area = 32, this would be:

8 * x / 2 = 32

Now, solve:

8x/2=32\\4x=32\\x=8

I don’t get this one but the question was something about finding the equation.
Alina [70]

9514 1404 393

Answer:

  y = -(x -3)^2 +2

Step-by-step explanation:

The vertex form of the equation for a parabola is ...

  y = a(x -h)^2 +k

where the vertex is (h, k) and the value 'a' is a vertical scale factor.

The value of 'a' can be found by looking at the y-value of points ±1 either side of the vertex relative to the vertex. Here, the vertex y-value is +2 at x=3, and either side goes down 1 unit (to y=1) for 1 unit to the right or left. So, a = -1.

Using the values we've read from the graph for the vertex (h, k) = (3, 2) and the scale factor a = -1, we can write the equation as ...

  y = -(x -3)^2 +2

What is 36j + j<br><br> please help and explain if you can!!! :)
Norma-Jean [14]
36j + j = 37j

Explanation.
You could translate this sum into a normal sebtence: I have 36 apples and add 1 apple more.

The sum will then be 36 apples + apple = 37 apples.
Replacing the word (in this explanation 'apple') by a letter learns us 36a + a = 37a

Hence 36j + j = 37j

Given that f(x)=6x+2 and g(x)=2x+4/5 solve for g(f(1))<br><br> A.1<br> B.3<br> C.4<br> D.8
GrogVix [38]

Answer:

The value of g(f(1)) is 84/5

Step-by-step explanation:

To find the answer to a composite function, start with the function on the inside, which is f(1). So, we input 1 into the f(x) equation and evaluate.

f(x) = 6x + 2

f(1) = 6(1) + 2

f(1) = 6 + 2

f(1) = 8

Now that we have the answer of 8, we can input that in for x in the outside function, which is g(x).

g(x) = 2x + 4/5

g(8) = 2(8) + 4/5

g(8) = 16 + 4/5

g(8) = 84/5
