The numbers are 16 and 4

Reason: 16+4=20 and (16*3)-(4*2)=48-8=40

Calculate cos theta to two decimal places. <br><br> A. 0.69<br> B. 1.38<br> C. -0.07<br> D. 0.77

alexgriva [62]

Answer:

A. 0.69

Step-by-step explanation:

We need to use cosine theorem:

c²=a²+b² - 2ab* cos(θ)

c=8, a=7, b=11

8² = 7²+11² - 2*7*11 *cos(θ)

64 = 49 + 121 - 154*cos(θ)

64 - 170 = - 154*cos(θ)

- 106/ (- 154) = cos(θ)

cos(θ) = 0.69

The lengths of the sides of quadrilateral EFGH are as follows: EF = 12 cm, FG = 6 cm, GH = 9 cm, and EH

vampirchik [111]

The true statement about the side lengths of quadrilateral MNOP is (d) MP = OP = 11.25 cm because the scale factor for dilating quadrilateral EFGH is 1.25.

The side lengths of EFGH are given as:

$EF = 12\ cm$

$FG = 6\ cm$

$GH = 9\ cm$

$EH = 9\ cm$

Length NO is also given as:

$NO = 7.5\ cm$

Because both quadrilaterals are similar, then side NO corresponds to side FG.

The scale factor (k) from EFGH to MNOP is then calculated as:

$k = \frac{NO}{FG}$

$k = \frac{7.5}{6}$

$k = 1.25$

The side lengths of MNOP are then calculated using:

$MN = 12cm \times 1.25$

$MN = 15\ cm$

$OP = 9cm \times 1.25$

$O P = 11. 25 cm$

Also,

$MP = 11. 25 cm$

So, the true statement is (d)

Find the area of the square in inches2 and enter your answer below. Do not include units in your answer.

saveliy_v [14]

Answer:

11.56

Step-by-step explanation:

The area formula is just Length * Height. Since this shape is a square, both the length and height are equivalent to the same thing, 3.4. So, all we have to do is multiply 3.4 * 3.4, or we can do 3.4^2.
