Answer:

Answer: x is 5 units

Step-by-step explanation:

» From trigonometric ratios,

{ \tt{ \red{ \sin( \theta) =  \frac{opposite}{hypotenuse}  }}} \\

  • theta is 45°
  • opposite is x
  • hypotenuse is √50

{ \tt{ \sin(45 \degree) =  \frac{x}{ \sqrt{50} }  }} \\  \\ { \tt{x =  \sqrt{50}  \times  \frac{1}{ \sqrt{2} } }} \\  \\ { \tt{x =  \sqrt{ \frac{50}{2} } }} \\  \\ { \tt{x =  \sqrt{25} }} \\ { \boxed{ \tt{x = 5 \: units}}}

Or, from pythogras theorem

{ \tt{ {a}^{2}  +  {b}^{2}  =  {c}^{2} }}

  • a is x, and b is x
  • c is √50

{ \tt{ {x}^{2}  +  {x}^{2} =  {( \sqrt{50}) }^{2}  }} \\ { \tt{2 {x}^{2} = 50 }} \\ { \tt{ {x}^{2}  = 25}} \\ { \tt{x =  \sqrt{25} }} \\ { \boxed{ \tt{x = 5 \: units}}}

Answer:

  • Option A

Step-by-step explanation:

We can solve this with the help of Pythagoras theorem.

  • => (√50)² = x² + x²
  • => √50 x √50 = x² + x²
  • => 50 = 2x²
  • => 25 = x²
  • => x = 5

Hence, the value of x is 5 units.

Factor 9y2 - 12y + 4.<br><br> (3 y - 2)(3 y + 2)<br> (3 y - 4)( y + 1)<br> (3 y - 2) 2
lozanna [386]

Answer:

(y - 2)²

Step-by-step explanation:

9y² - 12y + 4 ← is a perfect square of the form

(ax - b)² = a²x² - 2abx + b²

Compare like terms with 9y² - 12y + 4, thus

a² = 9 ⇒ a = 3

b² = 4 ⇒ b = 2 and

- 2ab = - 2 × 3 × 2 = - 12

Thus

9y² - 12y + 4 = (3y - 2)²

Can someone help me with this please
Anni [7]

Answer:

x = 61

Step-by-step explanation:

These 2 angles are supplementary which means they add up to 180:

2x - 6 + x + 3 = 180

3x - 3 = 180

3x = 183

x = 61
