Find the missing angle I think...

lara [203]3 years ago

Answer:

Step-by-step explanation:

Since this is a test/homework, I'll give you a hint.

A triangle always is 180 degrees. If you add up all the sides, it should be 180.

A horizontal line is 180, if you add up the two sides (or the "line" that is crossing through the horizontal one) it'll be 180.

Just think of it like this: 180 is king. No matter what you add together, if its not 180, its wrong.

Hope this helps!

64+45= 109
180-109= 71
90-71=19

Find the value of c that makes each trinomial a perfect square.
gavmur [86]

Answer:

The answer to your question is the letter a.

Step-by-step explanation:

Data

             x² + 12x + c

If this trinomial is a perfect square trinomial, the third term must be half the second term divided by the square root of the first term, and to the second power.

-Get half the second term

               12x/2 = 6x

-Divide by the square root of the first term

               6x/x = 6

-Express the result to the second power

                          6² = 36

-Write the perfect square trinomial

             (x² + 12x + 36) = (x + 6)²

Answer:

20 inches

Step-by-step explanation:

Since the cape is trapezoid shaped and has an area of 600 in², the area of a trapezoid is given by

A =1/2(a + b)h where a = length along the top of the cape = 24 in, b =  length along the bottom of the cape = 36 in and h = height of the cape

So, h = 2A/(a + b)

= 2 × 600 in²/(24 in + 36 in)

= 1200 in²/60 in

= 20 in

So, the height of the cape is 20 inches

<u>Using values found in MINITAB 19 </u>

a) The samples are dependent and this is because the title of the test is the same ( i.e. A group of students given the LSAT )

<u>b) Appropriate hypothesis</u>

H0: µd = 0

Ha: µd > 0

<u>c) The Minitab procedure to be used to test the hypothesis is </u>

click on Stat  --> Basic Statistics ----> Paired t. then select samples 1 , 2 to get the required output
