If sin x = 0.5, then x = sin^-1( 0.5) = 30°. This is also one of the special valuse of sine that you should have memorized. It makes it easier if you can just remember these values rather than calculating them each time (especially in certain no calculator tests!).

Answer:

<em>Answer is </em><em>given below with explanations</em><em>.</em>

Step-by-step explanation:

Answer is option 1) 85 : 51

given \: that \:  \\ triangle \: SPT \: is \: similar \: to \: triangle \:  QPR \\ corresponding \: sides \: of \: similar \:  \\ triangles \: are \: in \: proportion \\ then \:  \\  \frac{SP}{ QP}  =  \frac{PT }{ PR}  \\  \frac{3x}{3x + 24}  =  \frac{51}{85}  \\ taking \: reciprocal \: on \: both \: sides \\  \frac{3x + 24}{3x}  =  \frac{85}{51}

Option 1 is correct.

Equations, Their Slopes And Y-intercepts. Please 9,11 and 12 question! Thank you!)
MakcuM [25]

Hey there!

(9) 2x-9y=45

... -9y=-2x+45

... y = (2/9)x - 5

Slope = 2/9

y-intercept = (0,-5)

(11) 3y+2x=-15

... 3y=-2x-15

... y = (-2/3)x - 5

Slope = -2/3

y-intercept = (0,-5)

(12) 10x+8y=40

... 8y=-10x+40

... y=(-10/8)x+5

Slope = -5/4 (after simplifying )

y-intercept = (0,5)

Hope my answer helps!
