Answer:

Step-by-step explanation:

Triangle BCD is a right angle triangle.

From the given right angle triangle

BC represents the hypotenuse of the right angle triangle.

Taking 45 degrees as the reference angle,

BC represents the adjacent side of the right angle triangle.

BD represents the opposite side of the right angle triangle.

To determine BC, we would apply trigonometric ratio

Cos θ = adjacent side/hypotenuse side. Therefore,

Cos 45 = BC/2√2

√2/2 = BC/2√2

BC = 2√2 × √2/2

BC = 2

Math!!! help!!! will give brainliest to correct answer

My name is Ann [436]

x=8

Step-by-step explanation:

move the +2 to the right side so it can be subtracted by the 5 to get 3. after that you square both sides of the equation to get rid of the square root symbol. then move the -7 to the right side and add it with 9. then you'll have 2x=16. then divide both sides by 2 to get x by its self and you are left with x =8

solve the x:(pls help with explanation) 1. 2x/3=18 2. 1.6= x/1.5 3. 14y-8=13 4. 17+6p=9 5. x/3+1= 7/15

Answer:

1. X=27

2. X=2.4

3. y= 1.5

4. p=-1.33

5. X=-1.6

solution,

$1. \: \: \frac{2x}{3} = 18 \\ \: \: or \: 2x = 18 \times 3(cross \: multiplication) \\ \: \: or \: 2x = 54 \\ \: \: \: or \: x = \frac{54}{2} \\ \: \: \: x = 27$

$2. \: \: 1.6 = \frac{x}{1.5} \\ \: \: or \: x = 1.6 \times 1.5( \: cross \: multiplication) \\ \: \: \: \: x = 2.4$

$3. \: \: 14y - 8 = 13 \\ \: \: \: or \: 14y = 13 + 8 \\ \: \: or \: 14 \: y = 21 \\ \: \: or \: 14 \times y = 21 \\ \: \: \: or \: y = \frac{21}{14} \\ \: divide \: 21 \: and \: 14 \: by \: 7 \: you \: will \: get \\ \:or \: y = \frac{3}{2} \\ y = 1.5$

$4. \: \: 17 + 6p = 9 \\ \: \: or \: 6p = 9 - 17 \\ \: \: or \: 6p = - 8 \\ \: \: or \: p = \frac{ - 8}{6} \\ \: \: or \: p = \frac{ - 4}{3} \\ \: \: p = - 1.33 \\$

$5. \: \: \frac{x}{3} + 1 = \frac{7}{15} \\ \: or \: \frac{x + 1 \times 3}{3} = \frac{7}{15} \\ \: \: or \: \frac{x + 3}{3} = \frac{7}{15} \\ \: or \: 15(x + 3) = 7 \times 3( \: cross \: multiplication) \\ \: \: or \: 15x + 45 = 21 \\ \: \: or \: 15x = 21 - 45 \\ \: \: or \: 15x = - 24 \\ \: \: or \: x = \frac{ - 24}{15} \\ \: divide \: - 24 \: and \: 15 \: by \: 3 \\ \: or \: x = \frac{ - 8}{5} \\ x = - 1.6$

Hope this helps ...

Good luck on your assignment..
