Answer:

15/17

Step-by-step explanation:

cos(arctan(8/15)) = 15/17

You could assume the ratio values 8 and 15 represent the opposite and adjacent sides of a right triangle. Then the hypotenuse is ...

h = √(8² +15²) = √289 = 17

The cosine is the ratio of the adjacent side to the hypotenuse, so is ...

cos(x) = 15/17

LUCKY_DIMON [66]

Answer:

Step-by-step explanation:

since it is a right angle triangle

${x}^{2} = ({5 \sqrt{2} })^{2} +({5 \sqrt{2} })^{2}$

$x = \sqrt[2]{(5 \sqrt{2} )^{2} +( 5 \sqrt{2})^{2}}$

$x = \sqrt{(25 \times 2) + (25 \times 2)}$

$x = \sqrt{50 + 50}$

$x = \sqrt{100}$

$x = 10$

Answer:

The solution of the given equations are (3,2).

Step-by-step explanation:

Given equations are :

3d−e=7 ...(1)

d+e=5 ...(2)

Add equations (1) and (2) we get :

3d-e+d+e=7+5

4d = 12

d = 3

Put the value of d in equation (2).

3+e=5

e = 2

So, the value of d = 3 and e = 2. Solution of the given equations are (3,2).
