Can someone help me with this!

Answer:

Please read the answers below.

Step-by-step explanation:

Let's recall that in a square all its sides are equal length and all the four internal angles measure 90 °

5. If LN = 46, then we have:

OM = 46 (Same length than LN)

PN = LN/2 = 46/2 = 23

ON = √LN²/2 = √ 46²/2 = √ 2,116/2 = √ 1,058 = 32.53 (Rounding to two decimal places)

MN = ON = 32.53

6. m ∠EFG = 90°

m ∠GDH = ∠GDH/2 = 90/2 = 45°

m ∠FEG = ∠DEF/2 = 90/2 = 45°

m ∠DHG = 180 - (∠GDH + ∠DGH) = 180 - (45 + 45)= 180 - 90 = 90°

7. Solve for x

6x - 21 = ∠PQR/2

6x - 21 = 90/2

6x - 21 = 45

6x = 45 +21

6x = 66

x = 11

For an angle θ with the point (15, −8) on its terminating side, what is the value of cosine?

malfutka [58]

Answer:

The value of cosθ is $\frac{15}{17}$

Step-by-step explanation:

It is given that an angle θ with the point (15, −8) on its terminating side.

Here x=adjacent side=15 units and y=opposite side =-8 units,

Using pythagoras theorem,

$\text{hypotenuse}^2=\text{base}^2+\text{opposite side}^2$

$\text{hypotenuse}^2=(15)^2+(-8)^2$

$\text{hypotenuse}^2=225+64=289$

$\text{hypotenuse}^2=17$

Cosine is defined as

$\cos \theta=\frac{base}{hypotenuse}$

$\cos \theta=\frac{15}{17}$

Therefore the value of cosθ is $\frac{15}{17}$ .

What is mathematics

Blababa [14]

Mathematics includes the study of such topics as numbers, formulas and related structures, shapes and spaces in which they are contained, and quantities and their changes. There is no general consensus about its exact scope and its epistemological status.
