How do I find the missing angle?

To find the missing angle first we need to fill in the other angles.
If we look at the 128 its on a straight line that is separated by another straight line so to get the angle on the other side of the line we need to subtract 128 from 180 which is 52. 
The same goes for 160 so 180-160 = 20
And again the same for 60 so 180-60 = 120
So now that we have 2 out of 3 angles in the triangle we can figure out the final one by subtracting 120 and 20 from 180 (because theres 180 degrees in a triangle) which equals 40
Now if we look at the 40 degrees the other side is its opposite which makes it the same degree, and now we once again have 2 out of the 3 angles in a triangle so go to the triangle with 52 degrees and 40 degrees and subtract them from 180 which would be 88 degrees.
Now we subtract 88 from 180 to get the missing angle that we need (because its on another straight line thats been separated by another straight line) which equals 92

So the answer to your question is 92 degrees

Helen owns her own orchard. She plants 3 fruit trees for every 7 nut trees.
gavmur [86]

Answer:

f =  \frac{3}{7} n

Step-by-step explanation:

y = 3 fruit trees

x = 7 nut trees

Constant of proportionality = k

k = y/x

k = 3/7

f = 3/7n

A rectangular field has dimensions of (2x-3) yards and (x+4) yards. the area of the field is 285 square yards. what are the leng
trasher [3.6K]

The area of a rectangle is given by the multiplication of its dimensions:

\text{Area} = \text{width} \times \text{length}

In this case, we have an exact value for the area, and two variable expressions for width and length. Let's replace the formula above with what we're given:

285 = (2x-3)(x+4)

If you expand the right hand side, you have

285 =  2 x^2+ 5 x-12

And if you move all terms to the right hand side, this becomes

0 =  2 x^2+ 5 x-297

This is a quadratic equation, since it is in the form ax^2+bx+c=0, where a = 2,\ b=5 \text{ and } c = -297

If you plug these values in the generic formula

x_{1,2} = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

you get

x = \dfrac{-27}{2} \text{  or  } x = 11

Let's see which dimensions they yield:

x = \dfrac{-27}{2} \implies 2x-3 = -30,\quad x+4 = \dfrac{-19}{2}

But the dimensions of a rectangle can't be negative, so we can't accept this answer.

The other solution yields

x = 11 \implies 2x-3 = 19,\quad x+4 = 15

So these are the dimensions of the rectangle

Arithmetic sequences.....u find the next term by adding
geometric sequence....u find the next term by multiplying

sequence 1 : arithmetic...common difference is -16
32 + (-16) = 16
16 + (-16) = 0
0 + (-16) = -16

sequence 2 : geometric...common ratio is 1/2
32 * 1/2 = 16
16 * 1/2 = 8
8 * 1/2 = 4
